I know that was already done and rejected, but the book version didn't and was approved. And I really don't know if this is still enough for him to count.
Why Doesn’t He Qualify?[]
He just doesn't do enough even in the book. While he is still very evil and cruel, he doesn't go over the baseline. The only reason for his book version to count was that he killed a coyote (I think it was a coyote), after he told him he would survive if he tells him where Mowgli is, but lied. Even if this is very ruthless and evil, there's still the fact that prevents Shere Khan from counting and is also included in the book and not only in the movie, the scene where he let the wolf cubs go even if he would be able to kill them, but didn't and don't even hurt them and just told them stories. A Pure Evil villain wouldn't do that.
Final Verdict[]
Cut to him.
