Think about this in evolution terms. When our ancestors suffered major injury, they usually died, but shutting the wound as fast as possible gave the best chances of survival. People who survived accidents could still have offspring and were albe to pass their genes. On the other hand if your serious wounds would keep regenerating, this means whole process has to take more time, more energy, and needs care. So in our mind we can see, that it would be more beneficial in present times, but evolution does not see. Its just what gives you best chances of reproduction. And it turns out its not regeneration for us.
