Why do people mistreat their children when they know that?

It's these same kids who will get to throw them into a deep, dark, hole somewhere when they're too old to object?

For instance… I'm staying on good enough terms with mine so that they trust me. Then, when they're old and THEY depend on ME it's revenge time.

I'm going to find the dirtiest, most neglectful/abusive nursing home I can, and pick them out a room with a view of a brick wall, or a cemetery.

I'll visit once a year and regale them with stories of my childhood- just so they know exactly why they are there.

Horrible parents- did you not think of this?
Abused children- You're welcome.

Added (1). I'm not some brat bitter over an iphone:

I'm a 30 year old man and I've been planning this since I was lifted off of the ground by my neck and beaten with a weightlifting belt.

The children are not mistreated. They are being conditioned for life. Life is unfair. Member that.

You need to get some help. Its bad that you were abused but taking revenge won't solve anything.

Jst make sure you do not get ill first it does happen I do not blame you
Just remember that they are only people and you should forgive them the hatred you harbor will only fester and make you ill. Do not have to gorget just forgive

Because 95% of the time, that doesn't actually happen.

It would just be better to get counseling.

Don't stoop to there level.
