Yeah, sure. SJs don't sit around for years waiting for some kid to come around, then invite them on an adventure.
1) Luke was not just some random kid
2) Kenobi did not want to go on a random adventure
3) Because of prior knowledge and obligations, Kenobi's sense of duty caused him to offer training in the force to Luke for the good of the galaxy.
4) There is a will of the force, which kenobi most likely recognized, and which led to the events you are talking about.
You're taking a character at one point in time, disconnecting him from all previous events and characteristics, and making an evaluation on that. I don't think you're analyzing enough.
Kenobi during the clone wars was known as a methodical and cautious general who used superb plans for his victories, while also being very orthodox with respect to the jedi code--this very measured person is different from your portrayal of him as an old man looking for random kids to start trouble.
Everyone thinks Vader's an ENTJ- but I beg to differ..
Look at his past, and really analyze him. After seeing the most recent episode I think it safe to infer that he may be ENFJ or ENFP- he would have done anything for his wife and baby- and took revenge for them- something I think an F would be more prone to do.
I could be way off, but I don't think it's as obvious as ENTJ, just doesn't work like that- you can't just assume he's one if he's an evil dictator. You've gotta look into him and understand where he's coming from- and you'll understand.
Is it that by its indefiniteness it shadows forth the heartless voids and immensities of the universe, and thus stabs us from behind with the thought of annihilation, when beholding the white depths of the milky way?
