Another framing I like to keep in mind, as inaccurate as it might be:
In the show, more-so than the books, Moraine’s opening dialogue comes across as judgmental of Lews Therin and the 100 companions, as if the women Aes Sedai had any other option at the time. But the reality of the situation was that everyone was mostly clueless about how to seal the DO’s prison (no one intended to use the True Power) and they were running out of time. So Lews Therin acted, and the consequences of that action were immense, but it was done in a state of emergency. If anything, I think Lews Therin is judged more on the outcome of his actions than for the actions themselves, in both book and tv show.
