It wouldn't end there, of course. Once you accept the basic logic, you use your money out of Chelish Project revenues to buy a +4 / +4 headband - from some Lawful Evil merchant, under current theories wild guesses of harm reduction - and get whichever stat you're missing enhanced by scrolls or hired wizards on a regular basis.
And the price? However much of yourself changes, is lost, as the result of an abrupt and addictive enhancement like that.
If Keltham wanted to stop being this Keltham, if he despaired of being too small and too stupid for a world this harsh, it would be a more appealing option. But Keltham has always been fond of his self, see, rather fonder than most dath ilani; that's part of what being selfish is, in his own philosophy of that. Sort of an anti-Pilar, really; Keltham has some internal dissatisfactions, but he does not particularly have any part of himself that he'd want burned out of himself with fire, at all, let alone because he thought that he deserved it.
Three exits from this world.
One exit from himself.
