Start small and work your way towards your end goal. Serial and spree killing is a great first step.
Or pick up a few degrees in epidemiology/virology/genetic engineering and create a perfect virus. It's really not that hard to exterminate humanity.
Alternatively, build a series of small rockets that can put things in LEO with enough fuel to escape Earth's orbit with surplus for the mission, build a series of space drones that are capable of reaching the asteroid belt and landing reliably, and use multiple drones thrust to propel said asteroid towards the planet. If you can move a big enough rock, and accurately land it on earth, you really would be God. This would mostly likely not only kill all people, but possible end most life on Earth. For practice, I'd recommend playing Kerbal Space Program.

In order to kill everyone, first you must kill your self, grasshopper.

This is a classical scenario in which the only course of action that is prudent would be to Molotov everything.
