Are they, really?

Poor folks go through a lot as a result of being poor. It's hard to express how miserable the constant stress is, and it's not hard to understand how constant stress and the things we do to try and cope with it directly shorten lives.

Yeah, merely inflicting suffering on innocent people isn't quite as bad as killing them outright but it's such a small difference that I don't see a lot to be gained from trying to differentiate them.
