From the perspective of the Gazan parents, the worst of all should be Hamas (who is actually directly responsible for their situation) since they insist on poking the bear and getting Gaza into military conflicts they can't win.
You sound like someone who is excusing domestic violence by saying, "if she didn't want to get hit, she shouldn't have talked back".
Fuck Hamas, I don't support hamas, but like, Israeli actions in Gaza are clearly inexcusable.
