That's not evil, that's just kind of a jerky thing to do.
I could to that in 3 and NV (I think. I don't remember if there were caravans that actively roamed around in NV) as well.
I could do half of that in New Vegas and 3 and in 3 I could actively enslave people and sell them to slavers.
Face it, 3 and New Vegas had more quest options to do far worse things than 4 does. That's not an opinion that's an objective fact. In Fallout 4 my "evil" character is a jerk. In Fallout 3 and New Vegas were unquestionably evil people.
What's your point? It's still a terrible game.
