Is Sabretooth good or bad?
Sabretooth's senses and tracking abilities are just as good, if not better, than Wolverine and while his claws don't have the same range as Wolverine's, he's mastered a close-range fighting style that allows him to make up for that. All of his abilities combined would make Sabretooth an
efficient fighter of evil.
Is Sabertooth still alive?
It does not exist in the wild, only in captivity. And they can be huge, apparently the largest cat family member that has ever lived. The sabertooth tiger (aka smilodon) is a Pleistocene large cat predator that has been extinct for around 11,000 years.
