There were other areas where she had been narrowly looking ahead toward her goal that she had been unable to see those around her and not see any other paths available, but that had changed quite recently.
When Ash had such tunnel vision toward her goal, it was not so easy to think about the damage that could be caused or other available options that could be chosen from.
In many cases, it was not just that she could not think of those things, but it was that she did not wish to think about them, so it was easier to ignore that they existed.
She did try to set rules for herself and take actions to reduce the damage that she could do to those who were innocent or uninvolved with everything, but that was no longer enough for her.
It was difficult to deny the truth anymore as she became more aware of how her actions and inaction could lead to much suffering in the future.
