I get what you're going for but if you want to be realistic, the hostage taker wouldn't be surprised/upset in the third panel. Israel is undoubtedly committing war crimes but Hamas has made it pretty clear they don't give a shit if Palestinian civilians die.
I love the analogy if your loved one was being held at gun point, would you support the police firing through your loved one to kill the criminal? Yeah criminal is dead but like wtf.
Hey someone is robbing a bank, better blow it up. The customers and workers will die but at least we got the bank robber.
Depends. If the criminal was actively shooting at people and already killed a lot in a completely unhuman and grotesque way and has no intention of stopping? Probably be easier to understand
Hamas could let their people South and no one gets hurt. If Israel lets Palestinians across the border into Israel, Hamas will sneak in with them and kill lots of Israelis. Can you not see the difference?
