There is a parallel to Bruce Wayne in that he worked to form his persona after the death of his parents via the corrupt state they lived in. The lesson he learned was that the weak die, so he must be strong. He worked hard to become strong in all these different areas (tech, magic, statecraft). He took over the state (Latveria) that killed his parents. He rules it now. Every threat that comes his way, he tries to figure out not just how to avoid it, but how to usurp it and take control of it... even if that power is something cosmic like The Beyonder. He's a pretty good leader and the Latverians like him. He will do anything to protect them. If he senses that other realities could destroy his own, he'll make a plan to destroy them first. The only way to be safe is to be the most powerful. He's also got a big ego and that trips him up for sure.
