This is a extremely well done compilation of information gathered there about Chara, which shows that they are indeed the narrator. http://thefloweryfanclub.tumblr.com/post/143284030397/greetings-uh-so-ive-been-working-on-this Here a bit out of the "Chara can be corrupted" section:

There’s an interesting clue to the narrator and their state of mind when you check the bag of dog food in the lab. You see, unlike the dummy and tree, it’s affected by kill count, not LOVE. If you kill no one… Pacifist route text. You haven’t killed anyone at this point; the narrator is optimistic (”glass-full”). They’re having a good time on this path. They’re hopeful. After killing someone (even a single Whimsun, who won’t even raise your LV at LV 1)… The narrator is pessimistic. The bag is now “half empty”. Their state of mind is directly changed by you killing even one person. But if you kill Doggo, and your kill count is 21+…. The dog bag becomes funny. This is directly affected by killing Doggo and killing more than 20 people. The narrator doesn’t find his death funny before 20 kills. Something has changed in them. Their view on the world is directly changed by how much you kill. But they do not find Doggo’s death funny unless you kill more than 20 people (which is more than the equivalent of an entire area’s worth of monsters). They did not find it funny before the kills corrupted them, or they would always find his death funny, even without the kills.

 * (It is a half-empty bag of dog food)
 * (You just remembered something funny)
 * If you kill no one, they’re optimistic. They don’t want you to kill.
 * If you kill even once, they become pessimistic.
 * If you kill over 20 people then they can be sadistic, even on a non-genocide route.
