dying doesn't suddenly make someone a nice person, but still, I would at least donate SOMETHING.
an asshole's an asshole, but a human being's still a human being.
I wouldn't jump on the "HE'S SO BRAVE" wagon, but I'd at least feel a little bad for him...
No, cancer doesn't make him a hero, but... well... IT'S CANCER. if the guy's in school, that means he's at most in his mid-upper twenties. that's not even half of the average life expectancy (I'm goin by US numbers here, so around 75-80 something years old I think). Imagine that, your life isn't even half over, and boom, you're told you're going to die. Unless this guy was literally Adolf Hitler, I'd show a little bit of compassion. do you have to praise him? no. do you have to like him if he pulls through? no. would he do the same for you? who knows. but I atleast know that I'd feel good helping someone in need, asshat or not.
