We learn the benefits of helping others when we’re young so we might help people when we’re older. If you didn’t get help by anyone when you were young is it really that difficult to imagine that this person will not help others later on?
A different situation might be when you’re a parent and you want to give them everything you never had. But these are your children, not some strangers.
There are people who helped me when I needed help and there are people who didn’t, to the former I’m very sympathetic and I’ll help them in turn, to the latter I say piss off and I hope you die in a gutter!
Vicious circle? Possibly. Justified? Certainly!
