Yes, it would appear to be a fact that teachers do seem to be 'drawn' to some of these DCs- I guess they're not immune to their charisma. I recall an Australian research project where DC were anonymously asked to name the biggest bully in their class, in their opinion. Their teachers when then asked, also anon. to name the DC they liked most. The correlation was frightening...
I'm very glad that we appear to have moved somewhat away from what was a very popular theory not so long ago, that all bullies needed kindness, support and understanding, that they were all vulnerable. The reason they bullied was because no one understood them, see. Now, there's no doubt that there must be some DC who exhibit 'alpha', domineering, controlling and manipulative behaviour because they're 'compensating' for other stuff... but imho, the vast majority are just little shits who need a ! slap! They make their victim's lives hell, and even DC who might try and be supportive of the victim are scared to do so in case they, too, get labelled.
Interestingly, at work, I am 'superior' to two slightly younger women who treat me with the -ahem- deference and respect my position 'demands' 
. I absolutely know both would have been Queen Bee bullies at school, they radiate it even now. Both good looking, popular with the boys but with Ph.Ds in the catty remark, the sly put down, the scuttle-butt-mongering. I find them mid gossip behind semi-closed doors all the time. I am so glad I am in the position I am in BUT I absolutely do and will put them in their place when needed. I will not tolerate that behaviour, but then, these are allegedly grown women!!
