The good powers are better than the evil in the way of being good, as in you can throw bombs that handcuff weaken enemies defeating them and good gets to increase the bombs explosive range, plus you get energy from zapping people. as evil I had to zap dead bodies until they had enough charge for me to drain them to get full energy as evil you do get Ark Lightning. And that is better than the good version, but good gets to redirect missiles.
I loved beating an enemy handcuffing them and just lightly zapping them until they die you get more evil XP for doing executions.
I got Platinum for that game I had to.
