1. Cole is not an abomination
2.Wynne never attacked anyone unless the person did something morally dubious. Saying she is dangerous because she attack you when you try to annual the circle or desecrate the ashes is not a point being that any teach who care for their students would defend them to the death and any religious person would defend their religions sacred artifacts. You're just trying to catch her with loaded gun.
Wynne was an abomination and she kept her moral standards.
1.He is a mage or was and he is possessed so yep he is an abomnation...
2.Asunder shows crealy she can be pretty much unstable and snap out like justice sorry pal but turning into hostile abomnation isn't good as prove... As i said i don't care about moral standarts neither templar or chantry that is why they don't let "good" mages be free and imprison only "evil" mages...
Will you kill your character because they have a power that comes from the Fade?
If it is fade being or it is influenced by one yep... unless my inq is one then of course i will join army of demons and destroy everyone muahaha 
Because the series also made a point that everything is dangerous.
Yeah sorry im kung fu master and train peoples in it isn't im abomnation and can burn city and i will...
