Adrian's motives are petty in a way, wanting to avenge his father when he was a douche who profitted from other people's suffering. Family love can be blinding to the point that children overlooks the flaws of their parents, which is why Adrian sought vengeance when a "monsterous "bastard" murdered his father even though he was doing the world a favor. Did it occur to you that the fight between them was staged? I think they did that knowing Oliver would show up and it seemed like Prometheus allowed Artemis to cut his arm, and he then cut Quentin's arm to implicate him. I think that was all part of an elaborate means to keep Evelyn's cover safe and get Quentin to leave town because Adrian already had his scheme with Earth-2 Laurel planned out.

Did it occur to you that Adrian could have split-personality disorder? What if the fight between Prometheus and Vigilante on the rooftop was just in his head? It makes sense since Adrian Chase is traditionally Vigilante and yet he is Prometheus now, while there is actually a Vigilante running around. Also Vigilante always appears whenever Adrian isn't there. Yes there is the scene in 5x15 when Diggle, Rene and Curtis are fighting Vigilante while Adrian is across the street but I've watch that particular scene 4 times now and not once does anyone even glance at Adrian. I don't think he was actually there because he was Vigilante trying to kill Oliver across the street. Talia trained Oliver to "become someone else, something else" which led to him embracing the "Hood" persona but what if Adrian took this in the literal sense and he divided his mind in two halfs. One is a ruthless vigilante seeking justice no matter what while the other half is a vengeful murderer seeking justice for his father.
