It’s too hard, there isn’t time, someone might laugh;
To protect one’s family, to protect one’s honor, one’s children;
Kin selection; bad seed;
Original sin, intrinsic evil, fortune, luck, destiny, fate;
Sloth, avarice, envy, malice, jealousy, anger, rage, revenge;
For the hell of it
Because someone else might be taking advantage
Because
No one knows for sure
It doesn’t make any difference
It’s written in the stars
No one told us not to
We can get away with it
There’s no such thing as utopia
It probably wouldn’t work anyway
It might make some money
There isn’t enough for everyone
People don’t appreciate what you do for them
They don’t deserve it
They’re lazy
They aren’t like us
They’d do the same to you if they could
