My brother feels the opposite on having kids, but we have the same dad. Figure that one.
In general terms, your lines make sense, in reality...no.
it only means your father loved him more than you. That's why he has no problem reproducing it, and you do not want to reproduce it.
You should read about attachment theories and some psychogenealogy books. Everything you do or think now is conditionned by your past. Wether it's conscious or not.
There are stories of fathers prefering one of their sons (when they have two) just to reproduce what happened to them in the past when their own father prefered their brother to them . Most of these patterns are subconscious.
