The one who is colonizing the other. When Nate Turner killed children in his revolt it didn't make the slaves the bad guys and the slave owner the good guy. In the Indian Rebellion of 1857, resistance promised safety to British including kids and women but ended up attacking them, it didn't make the British empire the good guy and the Indian the bad guys

If you ignore the 80 years of oppression that preceded the Hamas attacks on Israel last year, the Israeli response has been one of genocidal intent. From indiscriminate bombings to cutting off supplies of food, water and other aid. They have directly killed at least 40k people, and likely many more from starvation and preventable diseases.

This could have been easily avoided by a simple prisoner swap. Israel has thousands of Palestinians detained without charge, and Hamas wanted to free them.

Where are you getting news, and how often?

I mean the whole reason why you are confused is that this is the most complex conflict in the world and here (like everywhere else) you are going to get responses in both directions. I suggest you read what each side has to say for itself: for unconditional pro-Israeli propaganda I suggest https://elderofziyon.blogspot.com/ and for unconditional pro-Palestinian propaganda I suggest https://mondoweiss.net/ – read both of these and decide for yourself what arguments on both sides you believe more.

I do not think there are any truly good guys in the conflict; but I do think that Israel is worse and tend to side with the Palestinians. This is mainly because Israel is the side with vastly more power and I think it's up to the powerful, the oppressor, to try to treat the people they have power over with dignity and try to give up the power they have.

Of course, even that argument of mine has a counter-argument! You can (and should!) read it here: https://elderofziyon.blogspot.com/2016/07/the-parameters-of-discussion-michael.html

War rarely decides who's right, just who's left.
