This whole post is just a contrived justification to senseless cruelty and suffering which is what often Morrigan suggest alias she was stupid evil in DAO,just as this post.
Point by Point:
1)Pointless explanation full of stupidity to try to justify Morrigan,sorry but you are alone here.
Just because you don't know someone this doesn't mean that you are allowed to go full genocide mode and then try to justify you by saying "i couldn't trust them so i killed them all" that's insane beyond any level that i can fathom.
The werewolves are little if nothing capable to control themselves,they are dangerous beasts who carry a mortal disease,whoever get infected by them become one of them or die.
Put in the same camp dangerous and infectious beasts is stupid beyond any level,the Warden army isn't more strong with werewolves is just more unstable.
What will think the others department such as the dwarves,the mages,the soldiers of Redcliffe of the werewolves during the battle?
Why they should trust dangerous and infectious beasts,who carry a disease poisonous as the taint?
A General and a commander like the warden must thank to these things,balance is necessary for coordination and power effectiveness.
Morrigan is stupid she is not capable to think on "long term" benefit this is why she suggest only the "immediate gain" without think to the consequences,this is the same stupid mistake she did with the ritual,underestimate her mother who she knew one day would come back to gain the price.
This choice and i think most will agree with me, is on a right/wrong binary,there is no grey here,help both by reediming Zathrian is the absolutly best choice.
Help only the Dalish is the 2nd best choice,help those beasts guided by a dangerous spirit is the worst choice,the stupid choice that only AListair in the darkspawn chronicles Dlc did,probably because he is not a good comunicator and he doesn't know on how to understand and talk with people and he didn't discover Zathrian's past and suffering.
THis is way the Warden is always the best,capable to understand others and made the better decision.
2)The only party members who suggest to abandon Redcliffe are:
Sten because he is not from Thedas and he doesn't care about the fate of Theodosian,but then again i have a low opinion and don't give a #### of someone who murdered an entire family who was only guilty of helping him to not die.
Stupid Morrigan as well.
Help redcliffe provide a series of advantage,there is the possibility to obtain more proofs against Loghain at the tavern one of his letters,there is the possibility for the Warden to improve his/her ability as a commander,a test to improve personal capacity of coordination of a small army,there is the possibility to gain more allies more soldiers for teh army (the villages as well as some knights) there is the possibility to gain more resources and to become more popular for the landsmeet.
Pretty much there is only to gain here,Morrigan who obviously doesn't know how things works in the outside world and is only concerned about the OGB toy doesn't care.
Then again i couldn't care less of her stupidity she is not a tactical mind and neither she is practical..
3) Again stupid choice corroborated by a contrived thoughts who use disadvantageous condition which are not mandatory in order to justify the sacrifice of the mother of a child.
I will talk from the worst possible scenario in order to lock that stupid way of thinking which is
go to Redcliffe and met Connor before to do teh circle quest.
Again the intelligent solution is to go to the circle of mages.
a) The Warden who is not a moron already know that the circle is in a bad situation since that there are rumors pretty much everyone about demons rampaging on the tower yet this si the intelligent solution,go to them instead to kill Isolde.
Why?
First sooner or later you need to do the circle quest regardless so is not even an extra effort,second you do not have any time limit to do that,the Warden do not have to care about Connor in redcliffe,is something will go wrong in the castle before of teh Warden arrival,there already the Knights as well as many other soldier in the castle who can kill Connor as soon as he show some sign of possession.
Then again if instead to listen to whatever Morrigan as to say you bother to gain information,more accurate informations the warden can go and speak to Connor,to understand that the demon or "lady" inside of him remain dormant in him if the boy is not threatened,she will only come if the boy is in danger.
So the deomn is not always capable to understand what's going on in the mortal realm,she only percieve the boy feeling,the more Connor is in his serenity the less chance the demon will come.
in DAI if the demon remained inside of him it remain dormant for 10 years,this proof that the demon is danger especially when you harm the child.
Kill the mother or the child without not even attempt to gain the lyrium first is the evil and stupid chice end of teh story,from all possible scenario or pointeview.
4)
if they can give you power, why not? Their death will not be wasted.
4)As actually anyone beyond me read this line from this user,are you serious or is this a joke?
First,who are you to decide what is worth to sacrifice for your own ends?
This is absolutely and unequivocally evil,exactly what that shrew of Morrigan suggested.
First you are trusting a mage that tried to kill you in his last attempt to survive after the crime that he committed,he try to save his ass by sacrifice the life of others,he need to learn that in Ferelden we don't want evil slavers.
Caladrius which was injured by the warden was not capable to perform any effective magic ashe even say,he will use his last strength,meaning that the magic is useless and with poor effective +1 Constitution.
For 1 constitution you are trying to justify the murdering of all of those people?
Are we fuc**** serious?
Sometime i don't even even understand as for why people want to justify what is evil and try to protrait it as a different thing...
5)That's just show on how incompetent you are about the characters.
Wynne isn't pro chantry as she said many times in banter with leliana,and she don't even believe that Andraste is a prophet,just an historical figure.
And kill people just because their lifestyle doesn't fit with your view of life is folly and whoever think like that need only to be put in straitjacket.
Seriously Morrigan suggest to kill those mages because she,and only she see them as not worthy to live,that's insane and whoever agree with her is insane too.
Also No need to find convoluted excuses here,she is a walking contradiction,first she want to see the mages dead for her bitterness then complain with Gregoir if this is done,she is stupid evil and doesn't even know what she want.
6)Again preserve the anvil is the evil and stupid choice.
First his creator Caridin want that destroyed he understand it better than anyone
second Branka is an insane woman who betrayed her whole army by using them as bait for Caradin's traps who betrayed her friend into becoming a broodmother,and yet only a moron will trust her with the anvil of the void who is used also to enslave the will of others,this is evil and stupid.
Let us not forget that in order to defeat a blight make to may sacrifice and stupid choices will come back to bite you in the future,kinda like what the stupid wardens of the 4th blight did,they killed their own griffins in order to defeat the 4th blight and now they are gone.
Sorry but i believe that "the ends justify the means" is just the convoluted excuses used by losers.
Preserve the anvil and you will be no better than a genlock ,enslave the dwarves and you will be guilty to be responsible of slavery.
7)ah trust that shrew of Morrigan with an old god soul after all of her malicious suggestion? Never!
