1. You’re under the assumption Luffy and Kid are the same. They share qualities, but they aren’t carbon copies. Luffy knows how to discern people’s intentions in a way Kid can’t/won’t. To start off, Kid wasn’t the one who wanted to team up with Apoo and Hawkins, it was Killer who suggested it from the start. Kid took what happened with Hawkins and Apoo as confirmation of his original thoughts.
2. I’m not rationalizing anything. I’m basing my thoughts on Kid as he has been written up t’ill now. While on the other, you’re not satisfied with Oda’s handling with Kid because it’s not congruent with your pre existing notions, such as Kid being stronger than Luffy.
