Just for clarification, by the second part of your statement do you mean to say that the people who seek knowledge in such matters will suffer as a result of their knowledge, or that they will become aware of their own suffering?
In my personal opinion a person should seek to be aware that suffering does occur beyond the scope of our personal interaction, but should not take great pains to immerse themselves in the suffering of others. Simply having knowledge of their pain is normally enough to allow one to empathize, and this ability to associate with anothers’ pain contributes to a healthy understanding of the self as well as identifying yourself to that person as a human who feels for their dilemma.
