After he's done with the criminals he will turn his attention to dissidents, then opposition, then he will start to do ethnic cleansing (genocide) against non Filipinos. This guy is dangerous. He's insane and a dictator as well. You guys think this is the answer, tell me in a few years what you think when your all living in fear of the gestapo.
I wonder about that too. what will happen in the next five or ten years? will he still bring "a positive effect"?
I don't think the idea can kill all criminals because it's just the world, criminals will be born even you kill them all. I mean, is he really sure it's a good idea?
