Good point, with the lock-on business, however the wall vs body doesn't prove anything. if you hit a wall with a sledgehammer, it doesn't just damage the area of impact, but also the area surrounding the impact as well. Materials like brick and concrete fracture outward and crater, while squishy humans tend to absorb damage mostly in the area of impact.
A man said to the universe: \"Sir I exist!\"
\"However,\" replied the universe, \"The fact has not created in me a sense of obligation.\"
