I wouldn't call it a grudge. Many SLEs tend to see the world of people as primarily fights for power, unless for some reason they have decided they don't care about it - perhaps because they feel so secure. Then they grow from Enneagram 7 into 5, becoming interested in learning about what interests them. A typical case is perhaps Marlon Brando, who according to all who met him had more of a jokey, I-dont-give-a-shit personality, all while playing around with pet projects.

But those who do see everything as a fight for power can be very annoying since, well, not everything is a fight for power for others.

Also, their impulsiveness in doing or saying things in the spur of the moment is also annoying to more rational types.
