Which behaviors have bad effects on a child's personality?

hello friends today i was studying a topic about kids. know i want to share some points from that topic.

1: Do not let the feeling of inferiority or superiority develop in the child.
2: Don't let children feel violence, avoid fighting in front of them.
3: Keep away from fear, it has very harmful effects on their development.
4: Learn to share your things or it will lead to selfishness.
5: Stop the child from comparing with others, like if the child says I want that toy that my friend has, instead of giving him that toy, give him something that he really likes and not someone else. Because of comparison, whatever change you want to bring about in a child, first become the same because children do what they see.
