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
That last paragraph doesn't work in a secret ballot system.
