"I don't think that can be right, it doesn't make evolutionary sense or something on those lines. "

A single punch can be lethal, so why doesn't a special case (albeit myth) of it make evolutionary sense?

I used to believe that altruism was generally faked.

What convinced you otherwise? I think the same person can profess either genuine or faked altruism depending on the situation. Figuring out the proportion of those throughout humanity without some kind of experimental psychology would be quite difficult I think.

Yes, but weren't human limbs also shaped by millions of years of fighting? I don't think you could determine the outcome of that evolutionary arms race a priori.
