Well I don't have to imagine what it is like, its not so much that you don't have emotions but that you don't experience them the way a 'normal' person would. Sai doesn't have a twisted personality and his calculative nature could just be a defensive mechanism he has to protect himself. Besides having a calculative nature is a good thing, I mean he is a ninja. He has also obviously gone through some intense emotional training and conditioning. Anyway just felt I should comment on this because I have that problem and I can assure you that I have no idea what people find offensive and it is a very difficult thing if you don't have experience with socializing especially with a diverse group of people.
I don't know why you would want him assassinated, sure he has his own division of anbu but he hasn't done anything that particularly threatens the position of the hokage or the well being of the village so there is no just cause in killing him. He didn't imply that she isn't fit for the position of hokage as a matter a fact I don't think he has a problem with that or he would've had some objections back when it was first suggested. If he has his own division of the anbu, and the village elders obviously hold him in such high regard, and he is such a cold, calculating militaristic person if he didn't want Tsunade to be hokage she most definitely wouldn't have been.Originally Posted by February
Secondly calling Tsunade Hime is not disrespectful, it is obviously something she was called when she was young because she is the granddaughter of the first thus earning her the status of princess. Others have addressed Tsunade as Hime in the past including Jiraiya of all people. Danzou is her elder, he was competing for the position of hokage against her teacher so to him she is a little girl, so while some might find addressing the Hokage like that to be disrespectful in his case it isn't.
