It is known that a judge is able to charge a juvenile as an adult depending on the crime they have committed, and there are many opinions on this topic. there are those who believe it is right, then there are those who believe it is simply unfair to send someone under the age 18 to an adult prison.
Kids and teenagers' brains are still developing, it is unfair to charge a juvenile as an adult if their mind isn't fully developed. Their mind needs to fully developed so they can understand what they are doing.
Most kids do not understand what there doing is wrong. They don't even get the concept of death because they are too young to understand. There are many kids who don't understand the meaning of death. They might cry at a funeral about how they are "gone" but later they still ask for the person not knowing the real meaning if death.
if they are of a young age and is tried as an adult, they basically had no childhood whats so ever. If they grow up with a punishment of a criminal then they are going to become one themself.
If a 5 year old were to commit a crime, everyone would strongly disagree with that. Then there was a 12 year old boy who killed a 6 year old girl and was charged as an adult. By the way he reacted with her death made it seem like he did not understand the meaning of death.
After the certain age, as a teenager, we all know from right to wrong. from ages 16 and up, they now understand what the concept of death is, and what is right and wrong.
No matter the age, their mind may just be in that dark place, and they will grow up the same way, they have a mentality of an adult committing a crime so punish them like one.
