Power can consume you if you’re not ready for it. With power comes great responsibility and what if he doesn’t want power but is forced? The poem questions power and in considering the machinations of it, draws it out conceptually as being a force of its own. As though a man in power who is ineffectual is merely a puppet.
I used the character of a gypsy king in order to highlight his folly over portraying power as an innately bad thing.
It’s not cryptic but it has depth which isn’t easy to detect I suppose. Its more about what is implied and not said. “Power is not a man” means to separate the concept of power from the character as a final valediction, though he is already condemned.
