Like all of Robert Jordan's characters, he's remarkably flawed and illogical, although he may get a pass due to slowly manifesting magic schizophrenia.

Counterpoint: He cut off a lot of monarchs' heads, abdicated his throne(s), broke all binds and oaths, saved the world, and despised slavery. Also all the bad stuff falls under the "literally going insane from magic" excuse, therefore uncritical support.
