Rofl'd at that. That's no excuse.
Stop being hypocritical, "PUH-LEASE".
Yes it is, it's exactly the point, we realized that robin was going to betray crocodile when she saved luffy, we knew that coribo was trying to kill the strawhats in his 2th apareance. Intentions
A villian who twirls his mustache to the audience is stating to US that he's evil. Like when Dio brando made that mom eat the baby's face, was to establish him as a complete monster. (minor plot point of something 20 years ago, not a spoiler)
A villian who just goes and does evil things and then we don't get focus of him will get the benefit of the doubt, because the AUTHOR is not telling us that he's evil. I don't have an example right now..
And I'm not saying Cariboo will join, don't be mistaken.
I just hate reading people bitching about those who want him to join. Seriously, what's the point? People think what they want to.
And stop deffending incredibly stupid theories just because you think that they are possible.
