Writing Remorse

I went on a rampage over the weekend and inflicted major devastations on three or four of my characters. The meanest perhaps was a double stroke on a lovely considerate female character. The first made her speak some repressed childhood language before she learnt to speak English again, and the second made her swear all the time. It was quite contrary to how she'd acted the whole story through.

I made her yell at the ladies from the church: "what are you dipshits staring at?"

I think I might have to revisit it. It is the first time I've ever felt remorse over writing and it's a very strange feeling.
