There's an important part of the timeline that we don't know.

In the Alpha Timeline, when Gaster didn't die in 201X, he and Sans would have bumped into Chara.

Remember that Elevator Voice (who I think is Gaster)  mentions the name we choose for Chara, before sending the elevator accelerating upwards at very uncomfortable pace.

What happened between Chara and Gaster? What happened between Chara and Sans?

Was there some sort of experiment that linked Chara and Frisk, and that's how The Anomaly got control of Frisk?

Regardless of whether he's forcing Chara to relive the most horrible moments of her life, or trying to break Frisk by forcing him to relive them instead, Gaster didn't intend for either Chara or Frisk to enjoy this.

I still think revenge for killing him is the reason, at least in Frisk/Beta San's case.
