Animal Cruelty leads to worse?

Its a proven fact that those types of people start out abusing/massacring animals, look at the facts. Most may not but they will not be stellar humans if left untreated.

what you are referring to is known informally as the trifecta. Cruelty to animals, bed wetting beyond an acceptable age, and criminal activity of a serious nature such as arson or forcing others into sexual situations. These 3 present in a child is often shown to usually result in criminal behavior later on in life. However, there is a maxim in psychology "you cannot use current behavior to definitively predict future behavior but you can take current behavior and see where it came from". you can have the trifecta present in a child and they can still grow up to be a respectable adult. and parents are not always to blame as explained by the biopsychosocial model stating personalities are built by biology (heredity) psychology (how we develop mentally in response to stimuli) and social constructs (friends, environs etc).

Usually this happens bc of neglect of the kid. Most do not become killers or rapists. If you look at statistics.

Depends on the person, really.
