How much force is required to stab someone?

For the record, I am genuinely curious, ZERO intentions to hurt anybody or any living creature here.
When you prep meat for cooking, there’s the difference in ease between cutting against and along the grain. But that’s also along the blade, and not with the tip of the knife, which I assume is used for the stabbing part.
Then for crime investigations, there’s also a distinction (I assume) between stabbing someone in defence versus stabbing someone to death.
In our body there’s a lot of layers, skin, muscle, organs, bone. How much force does a person need to stab someone? Is it the amount of force/number of stabs that determine whether someone was intending to stab a person to death? Can the amount of force used be determined post-mortem? Could an infant be able to stab someone with the amount of strength they have?
