Sure... the problems is that Suigetsu wasn't so much like that... he was always funny in my opinion but now Kishimoto is just making him look like a coward clown. He was supposed to be the reincarnation of the demon, who used to cut his victims limbs off before beheading them, remember?
I just got the feeling Kishimoto doesn’t know what to do with him so he’s just gonna make him run away... -_-
