10 Most Evil RPG Characters Of All Time

10. Dr Gavin Archer (Mass Effect Series)

Science is an incredibly important tool, especially in a sci-fi world - it's in the name, after all. Still, even those who will go to great lengths to advance the human race would agree that this mad scientist should never be allowed back into a lab. 

Dr Gavin Archer appears in the Overlord DLC of Mass Effect 2, and, boy, does he make an awful impression. This heinous Cerberus researcher oversees the titular scientific experiment, in which he forcibly imprisons his autistic brother in a mechanical prison and fuses him with virtual intelligence. This, naturally, leads to his bro experiencing constant, unceasing agony, which many would say is a fate worse than death.  

Now, while his actions are utterly unforgivable, he does show some remorse for them, which is why he sits higher on this list. Despite that, it's hard not to see the flawed man as pure evil, given the awful things he did to his brother.  

The fact that this jerk is only at the number ten spot shows just how awful things are going to get, so strap yourselves in.
