I think the best thing you can say is that Hamas has a non-military arm that has provided enough social services that Gaza didn't collapse in economic ruin over the last two decades. The much more obvious thing to say is that Hamas has run a nihilistic campaign largely focused on the murder of Israeli civilians, and that they are Islamist in nature (and thus opposed to secular democracy). (I'll add my personal opinion that I hope many of them burn in hell for the calamity they've brought on Gaza.)
