Asgore is most likely the main antagonist, but I believe the rest isn't correct.

If Asgore listened to Toriel, he wouldn't even have taken a single human soul. I believe you refer to Toriel's "suggestion" at the end of the pacifist route. She clearly points out that even killing a fallen human and then crossing the barrier to kill six more would have been better than what Asgore did, but that doesn't mean she have ever advised such thing, or that Asgore would have had the resolve to do it.

If Asgore listened to her, they would have taken care of any human they met. She clearly seems to believe it is the right thing to do. Without taking a human soul, the barrier would still stand when Frisk arrives.

We don't know, why Chara came back, so there is no way to tell how could it have been prevented.
