For starters, Hamas isn't control of West Bank, so you are trying to credit for not killing the people that had nothing to do with the Massacre.
I think you must be getting South and North mixed up... Gaza it highly populated in the northand that is where IDF asked them to flee from.. Problem is, there is no water or food down south... Hamas doesn't want them to move because IDF have a history of just ethnic cleansing areas and then letting/putting in settlers...
IDF have to own that history, that is a war crime and that is what causes these types of problems.
