Regardless of history, the attitude that he has displayed is that if someone who enjoys the misery of others. That personality would not be compatible with the good guys.

He could very well turn against Cinder if she started to treat him worse (she slapped Emerald in one of those black screen flashbacks in Fall didn't she? Something like that) as it could remind him of the abuse suffered at the hands of Marcus. But that would be for his own reasons and I doubt he would join the good guys after that.

Basically, I can't see him having a motivation to join the good guys, especially considering what he has done to them which Ruby realises at this point.
