This is a two year+ old post, but no one saw it, and I happen to like it, and it's my blog, and I'll cry if I want to!
NO, YOU DUMBFUCKS! It's the only reasonable and humane course of action under the given circumstances. Think about it. Man and his wife are working for a cartel. DEA offers them a bunch of money to be informants. The get a bunch of guys killed and thrown in jail and eventually get discovered. So, appropriately, the cartel goes to their home and kills them. Since there was no time to get a baby sitter, the couple's 5 year old witnessed the murder of his parents. Needless to say, he was a bit bothered by the event. So what do you do? Let the kid stay there with his dead parents for a while and eventually grow up a massively scarred and emotionally damaged individual? No, you show a little mercy and responsibility and kill the kid too. The guys didn't enjoy killing the child. It was a nightmare for them no doubt. But it was the right thing to do and they "manned up" and did it. My condolences to all involved. Yuk. But news people: WISE UP!
