Do you think there is such thing as a “bad” kid?

Before having said kids I would have said yes but since having my own I’m definitely not as hard headed and am a lot more empathetic, so my thoughts are constantly evolving.

I have certain memories of being a child and behaving what an adult would consider to be “bad”, but I can remember the reasons behind my so called “bad” behaviour, and it was usually the result of wanting attention, or feeling a certain way. I wouldn’t say those are bad things.

Do you think there’s always a reason behind bad behaviour, or are there some kids that are bad just for the sake of being bad? Is it a result of bad parenting?
