Readiness is the key word.
When viewing an 'evil', the task is to certainly refrain from wrongful action, including verbal attack or condemnation, but also to refrain from wrongful thought, in the form of mental condemnation or the propagation of fantasised doom weeds whose root is the 'evil' in question.
Love can be viewed as having two facets: benevolence (wishing others well) and beneficence (acting in their favour).
This is an obvious starting point but only a starting point.
When faced with 'evil' or some other obvious ill with an origin other than human malevolence, the mere fact of saying the following to God opens the door to a different path:
"Clean my heart. I trust that, when wrong motives and wrongful thinking are cleared, and self is out of the way, I will see what can be made of this."
If one cannot see, the only option is to pray and wait, trusting that the answers will come and mistrusting any path but this path of patience.
