I think barsoomcore had a lot of good comments on resolving this.
In my opinion, the key is in how you describe the NPC/Foe and his actions and, then, how you describe the emotions of his victims.
Add to this some 'meta knowledge' about your players and create a big old, emotional stew foe 'em!
For example, after describing the sick things that this evil foe has done to the women and children of the village (let them find a victim or two), then have them find old grandma. She is designed to tug at their heartstrings, bemoaning the fact that she only just played with little Johnny this morning! How could my little boy be dead?!
This might work even better if you first introduce little Johnny to the PC's in a prior adventure, where he does some minor errand work for them, fawning over the big heroes of the town. Give him a personality (one that is both serious and funny, making him memorable....perhaps he begins to dress up like one of the PC's and mimicing him/her).
If the PC's simply will not move on this, resort to metagame knowledge. Does one of your Players own a cat? A dog? Some kind of pet? Have your villain perform many obscene acts on these types of animals. Maybe they find a partially deformed dog, dragging itself through the wilds, whimpering because of the things that were done to it. Again, this only works if you can really ham it up, role-playing the heck out of it.
Finally, as a last resort, try to create a dangerous encounter and see if the NPC might be able to off a pc. That will probably get at least ONE of your players pissed at him=)
In my opinion, if none of the above work, you are out of luck.
