"In the other hand, it is great advantage for Chara: to have partial control over someone that is kinda unkillable. In that case helping Frisk has sense, especially when their goals are the same - killing."

That's my headcanon exactly. But remember, I'm posing this as a question to those who believe Chara isn't evil. As a response to UTLover's take on Chara. As you pointed out, this makes sense with an evil Chara. But with a "good" Chara? It doesn't work out. So, I'm basically using Reductio Ad Absurdum against the Chara is good theory.
