Forced sterilisation for people with an iq less then 120 and maybe gas them (latter depends on the cost).
With that i succeeded to decrease the scum of humanity by 98%

Are you sure that your iq is above 120? If a person offers to do so I'm not sure. These are signs of fascism. In Nazi Germany also destroyed mental not full of people and people with disabilities. You never thought about it?
Thats where i got my idea from. Stupid german nazis mananged only to gas 6 million jews, killed some 30 millions slavics and some more millions of subhumans.
If done right 98% would be no problem.
