I don't know, to me he seems more cold and calculating than that. Rational, but in a purely evil way.
For me there's some stuff in Star Wars films that I can just sort of ignore even though it's implausible, like Luke understanding R2D2's computer language and the domesticated tauntauns in the second film, but for certain things it just makes it harder for me to get into them because it makes it hard for me to forget that I'm watching a movie. It just sometimes seems like it's not a logical possibility at all.
