I know why I left Marvel but no one else in this universe knew or knows why. It may be of a mild interest to realize that Stan Lee chose not to know, or hear why, I left.

Steve Ditko is a brand name. It's not what I'm like that counts. If a person knows the what and whys, he knows all about the 'who' that is important to know.

I prefer conflicts that are based on reality rather than based on fantasy. When you get wound up with super villains, super fantastic gadgets and super incredible action, everything has to be made so deliberately that it all becomes senseless. It boils down to what you want a story to stand for. Every person, whether he wants to be or not, is in a continuous struggle. It is a struggle to keep his mind from being corrupted.
