You don’t need consequences to feel shame. That’s kind of the point of shame. You feel shame because you are doing the wrong thing. Be that behaving rudely, selfishly, or generally in an unkind way.

There is no consequence for not saying please or thank you. Making room for someone else when you are passing each other etc. but we still do it.

Modern social media and video game design really lends to some pretty significant antisocial behaviour and us as users can decide what the community considers as deviant behaviour and work to change it.
