Oh, brother... that is such a ridiculous arguement for abortion: "We simply cannot stop humans from killing each other, killing themselves, and a host of other supposedly immoral acts."
With that brilliant logic we might as well just legalize stealing and rape as well..because those will continue to happen no matter what the law says. To heck with all laws and morality...Everyone's going to do it anyway. Crank? Heroin? Prostitution? No problem!
Just keep on repeating your "feel good" logic. It's laughable. Fortunately your definition of logic is not what this country was founded on.
