id think of this topic as a nature/nurture thing.
someone brought up by caring parents would consider that to be the correct manor in which to act. such a person may enter the real life to discover that others are not like that, and that evil does actually exist. such a person could easily be corrupted by this due to their lack of knowledge about that.
the reverse could also be true. someone who is brought up knowing only to hurt, and see themselves in a caring society may be surprised at the reactions of those who are caring. this may make the person in question caring themselves.
of course, there are exceptions to this, and other situations where odd results occur. for instance, someone who is hurtful may repel the attention of those who are caring, which further inflates their desire to hurt.
on the flip side, someone who is brought up to be caring may find themselves with others who are caring. however this may then lead to instances where they deem themselves and their close friends to be better than others and only care for those who are close and scorn those who are not.
to be truly caring, you must find the spot amidst those extremes. with a working knowledge of what caring and hurting is, but also be brought up by those who know how to care. from here, one wouldnt be persuaded easily to hurt, as they would know what this does and the consequences to those actions. to compliment this, they would have been brought up knowing how to care for others and would be easier for them to care.
i do not believe it is necessarily a matter of embracing it. though to develop this, i do believe they must have a working knowledge of how the other works. to hurt out of vengeance means they once cared. and for someone to truly care for someone who was hurt by another would mean that they would be able to care on an empathetic level.
empathy brings on another topic, which then brings up more exceptions. see: sociopaths. but to prevent myself from straying too off topic ill stop here lol
