The straight evil path is murder hobo evil, that's why people don't like it. True to the originals, to be fair, but underwhelming in this day and age.
Having said that, it's certainly nice that a smarter evil, also known as lawful evil, can infiltrate the camp, torture fools and the like, just to sabotage it.
I'd honestly make it a quest, the sabotage, and also make it harder to even access the camp itself to begin with. Maybe to roam in it we'd have to first torture the mercenary dude, or complete some other unethical task, something like that.
