This is the answer why your inactivity shouldn't bother you: this issue is all about her. Whatever happened, it happened to her; therefore she should decide about the possible consequences as well. The real question is whether you wanted to beat the guy to serve justice in her name, or it's based on merely the indignation felt by the guy's action. If you really think about it, it's totally not the same. Regardless, I think she made her point of view pretty clear by that "'I don't want to tear the guy's family apart" story... And at the end of the day, every individual should be responsible for his / her own life, so if she doesn't want him to pay for whatever reason, then it's case closed. Even if you can't agree with her decision, there's nothing you can do, since as I said, it's all about her - her life, her actions, her consequences. Who would you be to override her will ... ?
