Please stop the emotional diarrhea. You have an intellect, so use it.
Reread my comment again and this time think about each word. You will find that "kill" or an equivalent word does not appear once.
What does appear is "genetic engineers". What do genetic engineers do? They create new organisms with genetic sequences chosen to encourage particular traits. Traits like intelligence and creativity.
Then we simply sit back and wait for the wild-type organisms to go extinct. No killing is needed, as even a few seconds of reflection would have let you find out for yourself.
I hold great hope that genetic engineering will have eliminated such people before then.
