Think of it as entertainment...
We have a guy who has his heart set on playing an FB, he's obsessed with having a 30 strength. At 9th level (minmaxed barb 2/fighter 2/cleric 2/some PrC that gives bonus to will saves). He already does around 80 points of damage on a crit, but has no AC and low hitpoints (80ish).
I got sick of playing the healer so we don’t have a healer right now.
Sooner or later he’ll frenzy. Then he’ll die. The game (Eberron) doesn’t have much raise dead.
But if it does then that’s also pretty good. In fact it would be awesome.
He rises to 10 becomes FB, frenzies, dies. Drops back down to 9th. Works his way back up to 10. Get’s FB again, frenzies, dies…. Rinse and repeat.
To his credit Mr. Min-max has freely said that the first time he attacks a party member he expects for the group to kill him.
He’s in it for the chuckles.
