What do you think about me burning barney the purple dinosaur in front of my little sibling?
What would you say is your motivation? Why did you do that?
I thought about it and debated to do what I thought was right.
It is wrong and hurtful to destroy some one else's belongings. It it not acceptable to emotionally torture your younger siblings.
I'm an adult and I felt like it
It makes no difference that you are an adult. It is wrong to do something that will hurt your little siblings. That includes hurting their feelings.
