Famous/Infamous Villains

I don't think the real Locke was ever a villain. Once he was "resurrected," it was Smokey/Man in Black using John's body. Ben Linus is interesting. He went from being a character I despised to being my favorite and one I actively rooted for, but it's hard to look past some of the awful things he did throughout this series.
The question for me was always what was Locke/what was Smokey?
The problem with that take is:
- it’s never entirely clear
- locke’s weakness as a person precrash (like not being able to choose Helen) is what made him a great vessel for MiB

It’s simil to why I picked Umbridge and not Voldemort- His evil is little without the Umbridges and Wormtails of this world to give him power
