You know why the Blade took so long to even be a thing. They thought that what Zarkon was making was for the good of all Galra. And ... in a way, it was, wasn't it?

[There's no denying that. The Galra still can get whatever it is that they want.]

The problem is that it didn't mean good things for other people. Does Lotor actually want to give those planets a choice? It doesn't sound like he does.
