I would have to agree that over all the charters seen , Tommy is the best person to be Prometheus with Malcolm Merlyn Training him . I think Malcolm took some of the waters from the Lazarus Pit and revived Tommy . Tommy now has the blood lust plus Malcolm in his ear and training him to kill Oliver . Malcolm is doing this because Oliver took away the League of Assassins from him . Malcolm is also going to tell Tommy that it is Oliver ' s fault that Laurel died which is going to fuel his rage and give more motivation for Tommy to want to kill Oliver . And lets not forget the fact that Oliver cut off Malcolm ' s hand which just throws more fuel on the fire . Lastly Malcolm knows of the list which he has explained to Tommy which ties everything together . Even though when Tommy was dying , he forgave Oliver , the Blood Lust and Malcolm in his ear are to powerful . While Tommy was dying , Oliver said It should of been me and I think that will be brought up .
