Humans need to have a persistent world view. Without persistent world view I could not even use a spoon -- I would be constantly surprised by what is this thing in my hand, and what I am supposed to do with it. My current understanding is that purpose of the ego is to maintain the world view. In other words, it provides resistane to change to the current world view. It is supposed to work like soil works for seed -- provides some initial resistance to facilitate growth and make it possible for the plant to survie after it breaks through the surface. Therefore, ego is absolutely necessary part of humans. Killing it is not possible and even trying to kill it is not a useful aim. (I know, I have tried.) That said, there may be many problems related to oversized egos and learning to work with your ego is worthwhile.
