You'll be fine. If you find a sword or spear that drains life, give it to him so he can keep his own hp topped off. He'll deal melee damage for you, and he provides an excellent pool of hp for the others to use with Shared Life to keep everyone healthy. If he goes Insane, you don't need to cure it (the stats that are lowered don't matter to him, iirc).
Virgon84: I'm currently playing with a Cleric, Knight, Druid, Sorcerer. With Knight not having any magic at all does that hurt my party much? I have him set up to be a melee damage dealer right now and he tears through everything but that may just be at the start of the game.
Also, make sure he takes care of all of your miscellaneous skills, like Disarm Trap and Merchant. Letting the Knight handle all the "one character per party" skills for the party lets your casters focus their skill points on magic skills.
