This is a hard line to tow, this is not a conflict with a 'good guy'.
The Hamas charter that they were founded on is publicly accessible, anyone can read it. It directly calls for Jihad as the only answer, and directly say that negotiation is not an option. There is also a line referencing that judgement will not come until the Jews are killed. Israel is doing bad things but don't let that lead you to the conclusion that Hamas is okay. It's really rough.
