As I explained, Jesus didn't sin because he was below the Jewish age of accountability. He only did kid stuff.
For the same reason most civilized jurisdictions don't execute children for committing the act of homicide. For them it is not a crime.
Are you actually trying to tell us that 12 year children don't sin?
Mine sure did!
And if a 12 year old commits murder, under our laws he will still go to prison for possibly the rest of his life. Murder is still a crime even if you're 12.
