The answer is with you. What do you think? Do you need this kind of a compassion which described in Dhamma?
Do you really want to get rid from unlimited desires and the stress and restlessness comes with those desires?
Do you really want to get rid from the anger, sadness, hatred arise when the desires are not fulfill according to the way you wish?
Do you really want to know about the trap? Do you really want to know about the truth?
So, being compassionate or needing for compassion is totally your decision.
The one who realized the truth or seeing the truth, feel compassion towards to the one who still don’t realize the same. So they anyway spread their rays of compassion to the universe.
As this real compassion exists with the wisdom they don’t suffer when others don’t feel their compassion or ignore the truth. But they keep spreading their compassion as blessings towards all being, and support in every possible way to make them feel the same real happiness, peace & liberation.
So at the end of the day decision is all yours!
