Indeed, she is wrong in that she does not know how to deal with those that do not accept her other than making them suffer and die. But she is so indulged in this that she is sort of enjoying it and is unable to pull herself out of the phase of being unaccepted.. she is just digging her own tomb in other words.

We have not yet seen how she rules another kingdom which would accept magic.

Although despite this I do worry... she sentenced some of the Southrons to death when they fought Gwaine... now, that was a bad decision of the producers to portray her like that. Whoever wrote that part should regret it.
