Remember, a) John doesn’t choose page titles in order to give us spoilers. In fact, he often picks deliberately misleading lines of dialog for the page titles, and b) if she does redeem herself, it would likely be toward the end of Part 4, and I don’t think we’re quite seeing those titles yet. On the other hand, assuming Beate turns out to be the one who framed Lottie (as seems likely), she’s already a murderer (in the present), and it’s hard to see what kind of redemption she’s going to get. Although, I’ve been wondering whether Myomoto’s death may have been somewhat unintentional. Maybe she meant to frame Lottie for assault, but didn’t mean to actually kill him? Maybe his saw through her disguise, and she panicked, and used more force than she’d meant to? He WAS still alive when she left him, even if he later died. Maybe being responsible for Myomoto’s death, has driven Beate further into madness? And, of course, there’s the possibility that she’s been possessed by an evil spirit and isn’t actually responsible for her actions.
