"We did something this year that was not based on animosity"

This quote by Nikki Sixx is most likely describing a choice or action taken by him or his team in the previous year. It indicates that the decision or action was not gotten of spite or ill will, but rather out of a desire to do something favorable. This might indicate that the choice or action was secured of a desire to assist others, to make a favorable change, or to produce something brand-new. It might also indicate that the decision or action was taken out of a desire to move away from an unfavorable situation or to prevent a conflict. Whatever the case, it is clear that the choice or action was taken out of a desire to do something positive and not out of animosity. This is a great reminder that we ought to always make every effort to make decisions and take actions out of a desire to do something favorable, rather than out of spite or ill will.
