[Superman] How would one go about killing Superman?

It's for ummm... *academic* purposes. How would somebody go about killing Superman without using kryptonite?

Other than kryptonite, Superman is also vulnerable to magic. A magic infused attack will hurt him as much as it would hurt a human under normal conditions. He also seems to have some vulnerability to electricity. (The villain Livewire has hurt him using it.) He can be hurt by Parasite's power draining ability. There are some beings with enough physical strength to hurt him (Kryptonians such as General Zod, New Gods such as Darkseid and Kalibak, Doomsday, and so on). Darkseid's Omega Effect (a power beam shot out of his eyes) can also cause serious harm to him. Superman is also vulnerable to mental manipulation; he has been put under mind control by Darkseid before, and Manchester Black once gave him a seizure using his telekinesis to bend the capillaries in his brain.

tl;dr: Superman's known weaknesses are kryptonite, magic, electricity, power draining, superhuman strength, the Omega Effect, mind control, and telekinesis.
