I'm going to treat my 1 and a half year old sister badly.
Thats mean. Why would you treat a toddler this way?
I really hate kids under 2
It is evil and wrong to harm children because you don't like them. You should seek professional help if you have thoughts of hurting kids.
I don't think this is evil or wrong at all, I just want to tap her a bit.
Young children under a certain age are still developing and are very fragile. It's dangerous to want to hit a child at that age and can cause lasting damage. If you're having these kinds of thoughts you should tell your parents.
