Raedric is absolutely not crazy. He knows exactly what he is doing. He is a very, very bad man, and a very, very bad ruler. Here's a really easy way to tell the difference between a good ruler and a bad one: good rulers' lands are not on the verge of open revolt and kept in check only by mass indiscriminate public executions.
Raedric definitely deserves to die. That doesn't necessarily mean Kolsc deserves to rule, but at least he isn't a mass-murderer. It doesn't matter, though, because regardless of who you pick everyone dies. With that in mind, I would say that killing Raedric is extremely satisfying, especially after he brags about murdering his own wife in cold blood because she tried to keep him from murdering their child, all while he's in the process of squeezing the life out of his people.
Do it early on and you even get to do it again later!
thanks for all the spoilers.
