The problem is not ineptitude. He rejected their self evident wishes for a death they chose, revived them and subjected them to torture and experimentation that Mengele might approve of. I wouldn't wish the experience of having your head drilled open for cranial drug injections on my worst enemy. He's a torture porn peddler glorifying suffering instead of alleviating it, like Teresa of Calcutta.
No. There's a vast difference between cutting someone's head open to save their life because they'll be dead otherwise, and doing it to a totally okay, healthy living person with the intention of killing them.
