I don't see any clear good guys in this war

Ok so I would say that the rebel groups fighting the Chadian government would have to be the "good guys", but they have some questionable friends. They are aligned with the Janjaweed groups, aka the guys doing all the killing and raping in Darfur, Sudan. So the rebel groups are fighting to overthrow the Chadian government due to their poor human rights record, which they have every right to do, since their leader is a brutal dictator, but how can they justify being aligned with a group who seems to me to be just as bad? Also, am I just supposed to be posting facts and videos or making my own commentary?
