Why doesn't Renekton become a darkin?

I'm not entirely up to date with Renekton's lore just to be clear. But now that he is free and causing all sorts of chaos, why hasn't he been approached by his former comrades? I would think that the darkin would try to "recruit" Renekton to their side. Either by offering to show him how to use blood maigc to alter his body and enhance his strength or just be like "hey we know you hate nasus, well so do we, lets be friends again". It's just a thought. What do you guys think?
