My opinion is that only selfishness is legitimate. Again, give me a reason why not to. I care about my friends and family because I'm alive and get to experience the connection. I care about living in a safe society, and hopefully one that will treat people less fortunate, as I feel I have been given a shitty hand in many regards. This is all self interest. That all goes away when I die.

Edit: Also miss me with this "would die for my principles" shit. You're literally defending dying for something you don't agree with.
