People give money cause they want to make themselves feel better. It makes you feel good. You can justify it however you want but in the end it's an enlightened self-interest. You can tell me thousands of reasons why you donate but in the end of the line subconsciously is cause it makes you feel good.
I'm really not sure how to respond to this. Yes, helping other people can make you feel good. That doesn't mean you don't care that you're also helping them. There's nothing I'm going to say to convince you that not everyone acts only to benefit themselves, because clearly you've already decided that's how everyone acts.
And yeah you could think of me as a hardcore sociopath or myzanthrope
I have in fact called you nothing of the sort.
(which is funny considering half of you blubbering paragons would sacrifice humanity for another race if given the choice, cause teh humanity is so evil) but I would actually help somebody on the street if I can. I have no illusion as to why I'm doing it though - it makes me feel better about myself. I gain nothing else from it but personal satisfaction.
Again, I'm highly doubting at this point that I'll convince you others act for different reasons. I would caution you that imputing your own motivations and thought processes on to others is a fallacy, however.
So goes for the rest of the stuff - if you care about the whole world and every single person in it then go ahead and do whatever you want. I'm not blind and I'm direct and straightforward enough to tell you I don't give a **** if something happens to somebody I don't know or whatever. You can care about the whole world, the world doesn't care about you. If I can help my family or you, my best friends or you - who do you think I would help 
Why can't you help both? It's understandable you try to help the people you know first, but rather often that's not the only option.
So shut the **** up about the whole people volunteer ****. People die just because of your mere existence - people die on this world because you simply have a place to stay, food to eat and so on and there's not enough resources. You hurt people without you even realizing it. So don't give me the high bound moralistic crap because it's usually people that haven't seen anything outside of their comfortable home, neighbourhood and mommy and daddy giving them money. And even if such was not the case, it shows lack of experience.
No, I will not shut up. You clearly have a cynical view of the world, and I suppose that's fine. I do not. I try to make the world that little bit better, that little bit brighter. You can speculate all you like about why this is, if it helps you sleep at night to think I'm a kid that has never seen the horrors of the world, so be it.
You are fighting omni-potent or so supposed Gods that have been extinguishing all life in the galaxy for the past kajilion years without a single fail and complete success, that possess indoctrination and untold technology vastly superior to yours. There's absolutely no reason for everyone to make it from your squad none whatsoever. The Collectors were nothing compared to the Reapers.
Sure there is. Because they're awesome.

It brakes any suspension of disbelief for the whole crew to make it alive again.
So don't have the whole crew make it out. No one is making you keep the whole crew alive. Hell, in a lot of ways sending someone weak, like Mordin or Tali, to guard the crew on the way back makes less sense than sending someone who can take care of themselves. I fully expect there to be times when your squad can die, and I would not dream of telling you they have to survive. But I would like the option to make sure they do.
