Marnie's account would do her a favour if they showed regret in Marnie's place, not try and make and excuse. While most wouldn;t buy, it, it would still be better to say something like.. Marnie isn't like this, she's good deep down, she's easily influenced....blah blah blah.
I still find it very short sighted of some people to be laying all this blame at Marnie's door. If she's getting majority of the social media backlash, then people really have selective blame distribution, as Lewis and Bear were absolutely calculated in created this dare. There names should be coming up every single time that Marnie does in this whole event, not just hers on its own. She is rightfully getting blame, but don't save Bear and Lewis's blushes while doing so.
Marnie should have denied the dare and asked for another, but she wanted to fit in with the other two and when she looks back she'll regret not engaging her brain at the time she needed to the most. It of course shows how weak she is, but if people don't have any words of wisdom for Bear and Lewis (who aren't weak minded like her and) who enocuraged, laughed and mocked their way through the whole thing, then I've lost hope.
