Emotional reactions, at times, are proportionate to the intensity of the experience unfolding.
Though, that's not always the case.
Whenever you have been accused or have accused others of "overreacting," they or you have deemed the response disproportionate to the situation at hand.
Of course, people don't truly see things as they are, they see them as "they" are, through the filters of their perceptions, beliefs, and worldviews.
Emotional reactions are always contextually relevant!
It's easy to judge WHAT someone does and much more challenging to care about WHY they did or are doing it.
Empathy is the practice of allowing yourself to see the world through the eyes of another, but if you're critical of yourself, it's unlikely you'll extend compassion to another, because, how you do anything is how you do everything.
The truth is if you experienced their experiences and believed what they believed; you would do what they are doing.
Judgment, therefore, stems from a lack of understanding, and if you're not curious enough to understand, it's unlikely you would have been able to help that person anyways.
