Sparnage said:Yes, he certainly has what it takes to use it. Not only with his ambition to grow stronger but he seems like the type to stab Guts and everyone else in the back given the appropriate situation.
Another candidate for the Behelit would be Serpico. There is already a thread about it somewhere if he were to be the one to make a deal with the Godhand and it seems possible. To set it off could be Farnese dying or something else to set of a huge amount of negative emotions, and he doesn't appear to overly like Guts as has been shown in recent chapter.
I can't see why not, he has already been betrayed twice by both Griffith and Gambino, so fate could easily send a third major betrayal towards poor Guts's way. ;D
