To take on the suffering of children is a self imposed form of suffering.
Again nothing on the topic at hand.
I’m speculating on the right to inflict suffering onto others.
By your reasoning. (not that there is a you that reasons)
To take on the suffering on other lifeforms is selfimposed suffering so we should not care about/empathise childabuse, torture, murder, rape, bullying, animal cruelty, gruesome medical tests, horrible breeding conditions etc. Why care about others suffering, empathy is a form of selfimposed suffering.
Life is full of suffering.
It is also full of great joy.
Evidently your brain is focused on one of the above…...mine on the other.
I love being awareness and imagine that I will do that until the organism dies.
