Harry can be hard to write sometimes because he’s got a really wide emotional range. He tends to act on his impulses, and sometimes it’s just hard to predict what exactly he’s going to do next. And it’s not as if he’s the most rational guy in the universe. No, he’s done plenty of irrational things, all because of the way he feels at a certain point. So I end up thinking to myself, “Would Harry really do something like this? What if he was really desperate?”

So going on to the Unforgivables, I don’t think Harry would use them unless he really needed to use them. We know he’s not afraid to use them, that’s for sure, because we’ve seen him try Crucio on both Bellatrix and he *attempted* to cast it on Snape as well. So he’s willing to use them, but I think he’s only going to use them if the person is doing something really bad, or has just killed someone that’s close to him. Like, if someone tries to kill/does kill Ron or Hermione, for example, I’m sure Harry wouldn’t hesitate to use one of the Unforgivables. We saw how he reacted when Dumbledore died. He was desperate, and he was angry, like VERY ANGRY. But I don’t think that Harry would use Avada Kedavra. He’s impulsive, yes, but I think he knows well enough the difference between good and evil, but I really can’t picture Harry stooping to the same level as the murders of the people he loved. I can’t see him using the Imperius Curse, either.

Harry might use Sectumsempra again, if the time seems right, but I doubt it. He was pretty horrified at the effects of it the first time around, and I don’t think he’s all that comfortable with it. If it was someone he hated the guts out of, maybe he’d try Crucio again. Chances are that he’s not going to refer back to Snape’s potion book. I could picture Harry delving deeper into the Dark Arts. Not because he’s evil or anything, but because he’s being driven by very strong feelings of revenge and desperation. He’d definitely go into all that Dark Arts stuff, though he would likely use them for defensive purposes.
