Villain tag has this specific description: betray and deceive.
That's mean:
- Promise to help the elf but then take the money instead.
- Turn on stingtail
- Consumed Withermoore soul via dialogue
- Consumed 3 undead souls instead of free them (via dialogue).
- turn on slane dragon
- Attack people (in a quest) before start conversation with them.
- Lie to the elf near the alcove.
- Kill three pokers before they start conversation.
So i think in the end you mostly do kind of betrayal type of actions to get this.
Yea, I have done all of these except I don't think I talked to that elf in the alcove. But I did go back and kill her at some point.
