No, children are:
Satanists who do wrong as long as it gives them pleasure.
They have no moral standard outside of "this feels good to me, so its good".
Now, you ask if children should be tried as adults.
Obviously not.
If a 5 year old were to take a gun and shoot someone,
punishing a 5 year old with 10 years of adult prison would be obviously absurd,
As it doesnt contribute much to anything,
And children are often abused in prison.
Of course, I maintain belief that every being can be transformed into good person,
And that severe punishments arent means to do that and arent even morally justified.
