Theories on Belkar's death

[The Pilgrim]

I see three possible scenarios:

1) Roy uses Belkar as cannon fodder against the big villiains (as he was planning to do at the ending of DStP). Belkar plays along as part of his "fake teamworking" strategy (without noticing that he is being used as cannon fodder), dies, and Roy (who has never bought Belkar's ploy) just leaves his corpse rotting away.

2) Belkar goes BSOD because someone is threatening to kill/has killed his cat, and gets killed. Roy refuses to acknowledge that Belkar has died while following a somewhat noble sentiment, and leaves his corpse rotting away.

3) Belkar genuinely has become less evil and more symphatetic, puts himself in danger for the welfare of the party in good faith, dies because of it, and Roy still refuses to believe Belkar is any less than the same evil psychotic bastard that he has always been, and leaves his corpse rotting away.

Those three theories can be summarized as two:

1) Belkar fakes, and dies for trying to fake. The tragedy being that his ploy to fake character development was stupid as no one was going to buy it, and he would have survived if he had not faked.

2) Belkar converts, and still dies. The tragedy being that a last-minute character development isn't enough to cover for a life full of maniac murdering.
