I am not sure what you are saying, and I fear there is some sort of
misunderstanding here or at least a different way of thinking about the
problem.

What we achieve by killing a process is that we give the kernel more
flexibility in how it manages the available memory. It really doesn't
matter what you kill, all that matters is that some memory is free'ed
up again.
