I must be missing that part of my brain, because seeing other people happy doesn't make me happy at all, it makes me indifferent.
And I'm putting it logically, 1 million random people have a greater chance of helping me than 1000
And the people involved in the dying would try to fight back in some way, human nature. If I was one of the to-be-deads I'd fight back and say "Damn the world", because that'd be human instinct and all.
If I survived and the world was damned, it'd not justify the means at all. But it'd be my nature.
I say the end justifies the means, does not mean I always care about the end. Me dying would be for the best, but damned I wouldn't like it
