What’s the biggest tell that you’re looking at a very selfish and inconsiderate person?

They justify their decisions by stating that what they are doing is legal instead of having an ethical or moral defense of their actions.

I.E. They’ll shoot their neighbors dog when it wanders onto their property and claim it is their right to do so.

In fact, those who constantly go on and on about their rights tend to be selfish assholes.

Good people tend to be much better than the bare minimum that is allowed by the law.
