Kamahl's mentor, the dwarf weaponsmaster Balthor the Stout, had a bit of a change of heart as well.
Balthor the Stout art by Ron Spears
Here is Balthor in his prime: surrounded by the barbarians of the Pardic Mountains, getting them pumped up and ready to fight. A fierce warrior and hero among men.
That's not the end of the heroic dwarf's story, however.
Balthor was later reanimated, his only goal to seek revenge on the evil Laquatus.
Balthor the Defiled art by Carl Critchlow
This Balthor is at his most desperate: his undead form is a curse, but a way to get vengeance on Laquatus. Laquatus proves able to control the zombified Balthor, however, due to the remnant of Laquatus's champion still lodged in his body. (Ironically, the card Balthor the Defiled is quite a nice combo with a graveyard full of Laquatus's Champions.)
At the end, Balthor's disciple Kamahl, Fist of Krosa does him the favor of slaying him for the second time -- and Kamahl slays Laquatus with his Mirari-enchanted sword, leaving Balthor finally at peace.
