i think BHk is evil or maybe really confused my reason is beacuse when sora became a heartless it let out the other side of his heart BHK anyway if u seen axel in the traler i think he telling BHk thats hes not a full person just one a side to someone and tells him about sora that if u defeat sora u will become a full heart not a shell so thats why i also thinking thats why hes where sora he after to kill sora and also most of the pics bHK looks very pissed off and confused
