Nobody of us was there. Luckily. You honestly believe that Hamas indeed invaded Israel with the intent to take hostages and "get rid of the oppressors" (like they announced before they invaded) but somehow Israel itself was faster to murder off its own civilians? That's mental.

Do I have issues with taking civilian hostages? Of course! But that objective is diametrically opposed to going on a mass murder spree.

Let's talk about sick reasoning then. Do you think the 3,000 rockets (Hamas claims it was 5,000) they shot at Israel on that single day were meant to take hostages, too? Certainly not. Hamas has been, and still is, claiming responsibility for deadly rocket and suicide attacks on an almost weekly, now almost daily, basis. Mass murder is evidentially not beneath them. I doubt they would suddenly change their strategy when face to face with people they think of as oppressors. It's also not hard to imagine a sick reasoning behind it: "Fill up the car, kill the rest."

Edit: Just to be sure, before the next person responds without reading half the thread: What Israel does in the name of revenge right now can only be considered as war crimes and is clearly wrong. That still does not make any actions of Hamas rightful. There can be two bad actors in the same story.
