Why Kids Should Not Be Tried As Adults

Good morning/afternoon/evening. The negative position would urgently like to negate the resolution: Resolved - Kids should NOT be tried as adults. Let me being by putting forth the following definitions. A kid is an informal term for a child or young person, a child defined as a person under the age of 18 years old. An adult is denoted as a person who is fully grown or developed, that is, a person 18 years of age or older. To be tried is to be subjected to trial. Essentially, a kid being tried as an adult means that a person under the age of 18 years old should be subjected to governmental punishment. This is absolutely ridiculous. It is irrational and unreasonable to punish innocent and naive children as though they are fully grown and matured adults. This brings me to three primary contentions:
According to WiseTo Social Issues, children have not yet achieved full development of their brains and thus are less culpable for their crimes. Under the viable, credible, and accurate definition of child that I put forth in my introduction, the affirmative position of this debate is suggesting to throw 13-year-olds, 5-year-olds, and 2-year-olds alike in prison and is interested in subjecting them to exceedingly harsh punishments (like YEARS or DECADES of jail time). This does not seem like a sensible or reasonable consequence for people who have not matured yet - who have not yet learned entirely how to act flawlessly in society. It is unjust and unmerited to be reprimanding
