1) Better Parenting If you have a depressed, suicidal,son at home who likes killing animals... maybe you shouldn't have guns around the house. 2) Stop taking Young Boys hunting I know a parent who's 7 year old son didn't even know the Alphabet...yet he'd take his son hunting to kill defenseless animals. (Isn't that how serial killers get started???) What kind of moral standard will these kids have as they grow older? 3) Lack of Father figure (or lack of strong Father figure) Seems like a lot of the teen-aged mass shooters were being raised by women... Not strong women...but weak women (or weak fathers) who didn't seem like they could do anything about their sons behavior once their sons became teen-agers. Note: Not sure how parental weakness can be fixed.
