"Under conditions of peace, the warlike man attacks himself" -- Nietzsche
Now some have interpreted this in the literal manner, to suggest that a warlike man will self-destruct when there are no wars to fight. This is, of course, silly. Much of Nietzsche's work, like that of most great philosophers, was written with many possible interpretations in mind, and to latch on to the literal one betrays a lack of consideration.
No, the way to interpret this is in the metaphorical or figurative manner, to ask what it is the words might _stand for_, not what they literally mean. And in this case, just a few minutes' reflection will reveal the true meaning of the phrase given above. War, of course, is a violent state of being. Violence is abuse, and a warlike man is one who engages in abuse. And when there is noone else to abuse, a warlike man must engage in self-abuse. If you know what I mean, and I think you do.
I hope the way forward is now clear. There can only be one course of action for your paladin to take for the next five years. Good luck, and godspeed.
