New Killer / Survivor idea

I think it would be pretty cool to get a meta killer whos backstory is that he/she had originally been a survivor but went crazy and became a killer mostly due to the fact that the other survivors keep messing up gens or just failing over and over. He/she eventually gets to the breaking point and starts actively killing the other survivors so that they can find the hatch and solo escape.

On the flip side it would be cool to get a survivor who originally was a killer but after the n^1000 time kind of gives up and starts feeling bad for the survivors. The killer eventually becomes obsessed with only one thing, getting the experience to walk through the exit gates which leads them to begin helping the survivors each match and get 0 kills over and over.

So the entity switches their roles but since the killer now survivor had been sort of morphed into a grotesque version of themselves when becoming killer in the first place they retain some aspects of that as a survivor and so we could finally get a survivor that is deformed or "changed".
