@Kuroww it's like you're saying anyone who has a sense of morality is a pretentious person who wants to always stand on the moral high ground. Human nature is coherently greedy. The sense of morality is just another form of this. You don't help the wife who's been abused by her husband when she asks for your help though you know it. Of course, you're not legally obligated to help her. Nor are you morally inclined. If you just ignore it and say you never knew, no one could blame you. "Treat others how you want to be treated" is often referred to as the golden rule. Let's say you never helped her, and a few years passed. Maybe her situation got better, maybe it got worse. If it got better, you could've helped make it better faster. If it got worse, you could've changed that outcome for a minor inconvenience.
Suppose you're in a somewhat similar position but now you're the one asking for help. Let us assume the person you're asking for help isn't legally obligated nor inclined to help you. But still, the suffering is too much so you reach out for that thin thread of hope. But just like you did the person shuts their door. "Well karma" you think. You can't think differently cause you were offered to do something that would've allowed you to say "Why is life so unfair" in this situation. You could've helped the wife in situation one and when you didn't get help here you could curse god, maybe you could have thought at least you were better than this person. But the decisions you made led you to be abandoned like the scum you are and the worse thing is you can't complain about it.
