Why The Double Standard On Hamas Vs Israel?

I want to ask, why is it that those people in Nigeria condemning Israel for invading rafah because of hamas bad eggs, saying why will Israel invade the whole Palestines and start killing everyone ? Saying why will you punish the whole country because of the sins of few people?Really? But they're the same people that supports Nigerian soldiers when they invaded Delta because of sins of some thugs that killed soldiers? Same people supported Nigerian soldiers for invading the south east just because of the sins of some unknown gun men?
