correct, animal abuse, along with pryromania and bed wetting, is one of the 3 childhood indicators of serial killers
That would be incorrect, these "Indicators" might actually indicate something else which is common with serial killers, for instance perhaps abuse or negligence from a parent, not having a real parent etc That basically means that people could grow up after having all those indicators and not become a serial killer, on the other hand someone else might not show any of those indicators and go on a killing spree.
