If you are messing with someone, you are doing it to yourself. Because everything is linked together.
The other is you, you are the other.
I know, here in the physical world, between three dimensions it doesn’t LOOK like that, but once you can look through the scenery of relativity, you will understand that what you do to someone else you do it with yourself, too.

Two brothers on the beach, one is around 7 the other is around 13 years. The older didn’t go after the younger but stayed to watch the young people playing with the ball. The younger came back to ask the older: what is he watching? What is he doing?
The older just shrugged his shoulder and said: nothing. And: I’m waiting. The younger said:
‘Please’, with a begging voice.
But there was no answer. In his anger his lips curved to cry.
Then he ran into the cooling waves seeing his brother’s unconcern about him.

Siblings. From one body and blood.
Now they don’t listen to each other.
Maybe just now.
Or who knows.
We are all siblings even if genetics don’t link us together in our present existence while using the human body.
Yet we are siblings.
So what you do to someone else you do it to yourself.
Or what you don’t want for yourself, don’t wish it for another.
What you don’t do to yourself don’t do to another.
Not with action, nor with words, nor with deed, nor with thought.
What feels bad for you from someone else don’t do that to another, don’t tell another, don’t think of another. This is the only way to have peace in your heart.
As Jesus said:
If someone throws a stone at you, throw back a piece of bread.
If you do no harm you won’t be harmed.
If you aren’t captious, others won’t be captious with you.
Similar creates similar.
It’s up to you what you choose.
Because the freedom of making a decision is yours.
