Shouldn't we care only "What I think" instead of "What I + Others think"? Our own thoughts make something wholesome or unwholesome. Not what other's think. So, is there a need to care about what others think regarding a certain thing?

We can do good for others, but they might think that we do something bad for them. Isn't it their responsibility to think in a wholesome manner?

The title of this question should be "Should we care about what others think?", but I found a related question here:

Should we care about what others think?

However, it doesn't have any answers regarding this case (karma).

Kind regards
We should not harass other people, including with what is wholesome. The suttas say:


  Enduring patience is the supreme austerity, Nibbāna is supreme say the
  Buddhas, for one gone forth does not hurt another, nor does an ascetic
  harass another. Dhammapada 184
  
  Drawing in the mind’s thoughts As a tortoise draws its limbs into its
  shell, Independent, not harassing others, fully quenched, A bhikkhu
  would not blame anyone. SN 1.17


If we act with a wholesome intention, this is not wrong. But if we discover others are not interested in our wholesome intentions, we should refrain from harassing them &amp; care about what they think.

However, if we unintentionally offend them with our wholesomeness, we have done nothing wrong. As Jesus said: "Do not give pearls to swine; do not give the children's food to the dogs; they will turn to attack &amp; trample upon it".
