Personally, my favoured theory is that Crimson is Ozpin's rogue daughter. She dabbled with the dark and, in grand old Sith style, it consumed her soul. Maybe the original motive was jealousy of Glynda, her father's star pupil and personal student. Maybe she felt that she deserved that place and was trying to prove herself to him by gaining power over the Dark ways. This would create an intersesting personal rivalry dynamic between her and Glynda.

Being the sentimental sort, I would love for her to have a Face Heel Turn and Death Equals Redemtion moment before the end. Then RWBY bring her body back to the Academy and her father can at last mourn her after so many years.
