might be surprising but many kids at that age think like this.... no like the time from where they were toddlers uk.. They don't have the knowledge to see what is good o bad.. they choose what they like even toddlers behaviour are similar to that..and only their surroundings (like parents,わor whoever close) need to teach the difference b/w good or bad or else they grow up thinkin what they did is right...their parents failed to see the changes between the kids.. they couldn't even identify which one is which.. Ig there was sm negligence in their brought up which made them/him like this he thinks only he knows his brother better than anyone else so whoever is comin between them needs to be eliminated to the point his behaviour also includes incest is okay for him
oh yeah makes sense, thank you (i forgot my psych classes lol)
i am just curious how tf did he have that kind of mindset so early in his life jsjskjsjkjdjs
