Yeah, I think the relationship the host has with his/her Bijuu depends on the Bijuu's personality more than anything else. Just look at the difference between the Ichibi's personality and the Hachibi's personality and then their relationships with their respective hosts.
By the way, I don't think the Kyuubi is necessarily evil. By no means am I saying the Kyuubi is a good guy but the Kyuubi doesn't seem the type to go around wantonly attacking people and destroying things. As I see it the Kyuubi has been victimized long before this series even began. At first he was kept as a pet by Hashirama which, given Kyuubi's personality, must have been utterly humiliating. Then it was forced to follow Madara regardless of whether it wanted to or not because of the sharingan and while attacking the village under Madara's orders it was sealed inside Naruto by Minato and now it's pretty much forced to either help Naruto or perish.
Defend the oppressed Samson, defend the Kyuubi.
