Venom would completely kill Wolverine, based on just a few assumptions.a) Aside from the superfast healing, the claws, and the unbreakable bones, Wolverine is only human. Sure, tough and strong, but only human.
b) Venom is not.
There are very few ways Wolverine could bring harm to Venom, but all Venom has to do is strangle or suffocate Wolverine, and he has a great many opportunities to do so.
Plus, Venom can lift 11 tons. I don't know what kind of lifting that is, whether it's bench press or squat or power clean or what, but he is still very strong. A man with a reasonable amount of martial arts training, who is a reasonably good athlete, can put over 2,000 PSI in a kick. Assuming that venom can squat 11 tons, and assuming (generously) that a good athlete can squat 500 pounds...
11 tons is 22,000 pounds. 22,000/500 is 44. So 2,000 PSI times 44 is 88,000 PSI. 44 tons.
Do you know what happens if you are kicked with 88,000 pounds per square inch? If you are hit in the stomach, not only will your ribs break, but your insides will literally turn to jelly. That will break any bones that are even in the area.
A kick like that to the head will transfer so much shock into Wolverine's brain he will be immediately knocked unconscious, killed, or given a stroke. Into the throat, and his entire throat will be crushed, flooding his lungs with blood. Into the chest, and the rigid skeleton will absorb all the force, the vibrations causing serious damage to the diaphragm and the entire lung area. Wolverine cannot realistically hope to win.
