I also consider the moral and religious values. The main one's are Kindness and empathy, you understandthe situation the girl's in, and you think about what she might've been feeling. You don't like seeing someone being hurt while you can take action. Also Kindness, you care and want to help her because you don't want to be a bystander but you also want to stand up for her. You don't like the way she's been treated and you want the bully to be kind to others.
I decide to confront the bully, and tell her that I saw her peer pressuring another girl, into doing her homework, that it wasn't right, that she was threateningsomeone to do something that wasn't honest and kind That threatening someone isn't the right thing to do, and if you need help then that's not the answer. You should apologise to her, and hopefully you've learnt your lesson and you've realised that you're not being honest to yourself or kind to others.
I reflect on the decision that I made. The positive outcome worked after all and a lesson was learnt. To be honest to yourself and think before you do something, because hurting and threatening others won't benefit in anyway. Realising your mistake and changing, because you know your doing the wrong thing.
