Sorry to all the Betty supporters, but I can't defend her in this case.
*Spoilers Involved, maybe*
I know how you guys feel about Betty being hurt in this case, but she killed two people in cold blood. That's not an excuse for her to commit murder. Not only that, but she wasn't thinking about her own children &/or grand children that she had while doing that. Even one of her own daughters asked her to turn herself in in the beginning of the movie. One wonders why didn't she take the high road out & to find some other guy that will make her happy?
When it comes to being in love, from what I read in here, that Dan & Betty weren't truly in love at all. And if this was the case, why continue to be married to each other, or to stay together at all?
