Yeah .... Im trying to get the Villain tag but got the Hero one instead. Reloaded the game. Im killing everyone that looks me the wrong way and still gives me the Hero tag. In dialogs , im always an asshole , i aways let murder happen, let the bad guys go...... like what do i have to do ?
Why would you restart? As has been mentioned, you can have both tags, and all these tags do is open up new dialogue options.
Also, you're guaranteed to get the HERO tag if you
rescue anyone from danger.
