I've only been defeating the right side...

Those devil-like guys that bully Woody, I always end up defeating them from the right side. I wonder if that means the devil on the left side ends up scarring Woody's left trunk while I'm busy?! I think to myself, 'When I see them, I should defeat them from the left too...' but I always end up defeating them from the right side though () I'm playing with this weird obsession lol
