If I'm reading what you're saying correctly, it sounds like her only issue with magic is in magic that harms others. So, offensive magic or curses. And, it also sounded like you were saying she'd also have an issue with Transfiguration, since that's the class that changes one object or creature into another, temporarily. However, if she is against transfiguration, I'm unclear as to why, since there's nothing I'm aware of that indicates it harms the object/creature being changed into another thing.<br/><br/>Now, students learn about curses, but I don't believe they are allowed to curse or hex one another. Here's what the Wiki says about curses:<br/><br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">Like hexes, Hogwarts students learn only a few of them in school. However, students studying Defence Against the Dark Arts learn how to deal with them using defensive magic. Most curses can be blocked or lifted by a counter-curse, with the most notable exceptions being the Killing curse and the Cruciatus Curse, two of the Unforgivable Curses.</blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>So, I'm unsure that your character will have any issues with the magic she's being taught at Hogwarts.
