Lets keep it very simple, and cut through the bullshit.
1. As a parent, you set rules for your children...you let them know the consequences. You suppose to. In all aspects.
2. She snuck in a boy knowing how shit may turned out....she knew she was breaking the rules...nothing to comprehend with that.
3. She got caught, bf got killed, by her action...that was the result.
Mama may be go prison.
Did she know this would be the consequences? No, again. Nobody knows what the end will be. You cant predict the future....you dont get to pick how it goes when you fuck up...but you know its consequences for your fuck ups.
Thats with woman, man or child..
Nothing about whatever you said applies to her situation or whatever situation.
Its very simple.
