Remaining silent in the face of injustice is the same as supporting it.
Just being good-natured is not enough. If you are good-natured but fail to stand up to injustice, you cannot protect anyone. Instead, you will tend to be taken lightly, enabling those who perpetrate injustice to only grow stronger.
Sickness and death are unavoidable in life. To experience illness is not itself misfortune, but to be defeated by illness is misfortune.
