A very controversial opinion

The more the see, the more I see the more I learn, and the more I learn, the more firmly I believe that age doesn't matters. Hear me out.
I don't believe that just because someone is 18, they are mature and able to handle the consequences of their actions and just because someone's 12 doesn't means they MUST be forgiven because of their age, like, not even a 'should' but a 'just a kid, let it go' is pure bs. I think you can see where I'm going but for those who can't yet, let me get to the point, I think people should be held accountable for their actions regardless of their age.
Just because 18 makes them legally an adult, doesn't means they always have the emotional maturity to be called one. Being legal doesn't makes it okay, because one women were killed in the name of Witchcraft and god knows what else, literally for breathing. Nowadays, being a 'soldier' is romanticized when, literally, what you're doing is killing or getting killed, over a matter which could have very much been calmly discussed. So, we have a brain to think critically, and people are getting more and more shallow, I see people shouting in comments 'It's a kid! Blah blah' when the kid is worse than the adult. I truly get it, where these people are coming from. But, I've seen people forcing me to forgive a child(who's very much aware about the shit they did) and that's what pisses me off. We really should hold people accountable and if they don't understand what they did, verbalize what they did. Anyways, what I meant to highlight was that I hope people use that consciousness, nowadays labelled as 'overthinking'. Brain is made to think; stagnant water loses it's purity. Overthink, overthink and overthink until you get a solution. Sometimes there is no clear solution, but we can only reach there by thinking. And, literacy crisis is at it's peak, don't let unconscious and shallow people take over your mind. Be aware and awesome, haha.
