You are quite logical in this. Yes it is a good idea to filter friends if there are huge read flags of non-reciprocation.

But taking active revenge is usually reserved for actual evil acts that bring harm and damage. This looks to just be a guy that is not friend material and has no reciprocation ability.
Do note though that you are not entitled to an act of reciprocation. But you are free to find those who reciprocate in kind.
Does this make sense?
