I'm for torture. Like for years. But with people like him, it might dangerous if you can't completely suppress him. If he got the chance, he might retaliate even worse. But if it's possible to do it without him having a chance to come back, than he should be tortured so that he begs for death. But with only the medicine, it might be to expensive to keep him. They need a healer, who can even heal someone on the brink of death. Or at least an unlimited number of good medicine so that he gets the treatment he really deserves. so maybe just torture him a little even though he deserves it because of circumstances.
