Dante is 100% taking the red path because of course he is. Literally moments after the cast posts the "WELP THIS IS A THING" warning he is outtie to go cut down this god damn tree a second time. Hopefully taking both Trish and Vergil with him.

He is willing to team up with people, though he may warn those who seem a little less hardy to go back to the outpost. If they refuse he may decide to get a little more forceful because dying sucks and he'd rather not have anyone else experience that shit okay.
