Oh. That's pretty stupid of me. I seem to have earned the hero tag somehow and didn't even realize it - I don't know why, I honestly wasn't trying to be a nice person lol. I imagine its probably too late by A3 to lose the hero tag or gain the villain tag?
EDIT: After doing some cursory reading online, it seems you can get the villain tag by just absorbing a bunch of souls. Can anyone confirm?
Not sure if it's random souls, but I did get the villain tag several times after absorbing 2-3 souls yes. Not sure if specific named souls trigger it or something.
Thanks! I'll give it a try then report back when I can (later tonight.) It's probably worth noting though that, like Yun, I have already done a bunch of 'evil' things, even though I don't have the tag, so I'm still somewhat doubtful that that's what I'm missing.
