When It's Okay to Cross, When It's Not Okay to Cross?

How do we know when it's appropriate to be more aggressive, to be maybe even mocking? I mean, that's definitely something that happened in the Old Testament. And Jesus himself was like, you know, you brood of vipers. Our motives are not always as pure as Jesus is was. We'd like to overestimate righteous anger and unrighteous anger. But someone suggested this actually Dr. Rebecca Kona, who does a lot of stuff on virtue for her students.
