Did Jodo Kast get what he deserved?

I recently purchased Boba Fett Omnibus and initially wanted to read them in order, but ended up jumping ahead to read Twin Engines of Destruction since it's always been a story I've wanted to read first hand.

This comic features Boba hunting down his doppelganger Jodo Kast, who, as far as I'm aware, made his first and last appearance in Twin Engines (correct me if I'm wrong, please).

Now, I actually found Jodo an intriguing character, despite his cockiness and foolish choices. I think we can all relate to his desire to be the best, even though he did take a cheap short-cut in order to gain his so-called "fame".

As we all know, Boba wins the fight and leaves Kast for dead (well, actually Boba essentially blows him up, giving him no chance for survival). Do you think Boba's response was warranted, or should he have given Kast another chance?

I honestly felt this was Boba at one of his harshest, must brutal moments with his decision to trick Kast into thinking he might have had a chance to save his own skin by selecting the correct serum (a gamble, but at least it was some form of a chance). But instead he blows Kast to oblivion! I mean, sure, it was one heck of a bad ass ending to that comic, but I couldn't help but pity Kast just a little! I mean, I think he taught Kast a serious lesson by whopping his arse that if he left him alone Kast would have been too humiliated to ever consider donning Mandalorian armor again.

Thoughts? Or was Kast simply someone who did not deserve a second chance?
