Should Children Be Tried As Adults?

Should children be tried as adults? I believe that by a certain, say 13, a person is fully aware of what is right and wrong. I have read many cases that involved 13-17 year olds committing horrific murders and they get sent to a juvenile facility, which is a slap on the wrist. I think that they should be tried as adults for murder, as for other crimes, I'm not sure. When someone commits murder they take someone's life that affects many family members and friends. So I definitely think that the person who committed the murder should be severly punish and not just sent to a juvenile facility. There are many children that are in and out of juvenile facilities because they don't learn the first time. They say that they learned that the juvenile system wasn't very strict so they went on committing crimes. I think that every murder case committed by a person under the age of 18 should be carefully evaluated and be on a person-by-person basis because mental capacity and things like that have to be considered. I know that when I was 13-14, I clearly knew right from wrong and that if I violated a law, I would get punished. I think society gives to much sympathy to children under the age of 18. I also believe in rehabilitation, so I don't think that children should get life without parole even though 42 states have laws that allow them to convict children with life without parole. Oklahoma can convict 13 year olds as adults for certain violate crimes. I think that there a lots of problems with our legal system. What do you think about convicting children as adults and for what crimes?
