Is it normal to tell someone not to do something yet do that thing

to another person or to that person ?

(like to do the same to that person or another while telling that person not to do that thing ?)

I am kind of a leader in life with a strong personality and lots of fans and followers , so it's only natural that i am attracted to the same kind of people .

Is it normal that i found out that a person was making fun of a girl on a blog saying she's retarded and other things ,so i told that person that he/she wants to destroy that girl that's why the blog was written , and that girl is actually intellgent (and because she's someone popular and important in the society )so i told that person that i have told the right authorities ,YET i DO THE SAME THING , writing more than one blog targeting a person indirectly and sometimes directly , part of it is because that person isn't that important , i'm kinda of a narcisisst who defends other narcisissts and talk about those less than me . is it normal to tell someone not to do something yet do the same to that person (whom i told not to write about that girl ) or to another person ?
