Generally I find it better to control what capacity for emotion I have left, rather than make a revealing display out of whatever pain might be there.
But there are exceptions.
Tears fell once this year when I lost a family member. Tears fell seven years ago when I lost a family member. Those are the last two times I can remember. Even then, it was to myself. Those two people were rooted in my childhood, meant a great deal to me, and helped me build up the person I am now. So, it wasn’t just me in pain, but childhood me, and every version of me since. Memories, mourning memories.
Usually I am far better at handling pain and death. Let’s just say I know it well enough to have built up a tolerance, that most of the time when horrible things happen I just handle things expressionless and without emotion.
As for other people…. I would encourage something similar, to be honest, especially in males. Though… I do not expect it. I have lived a certain kind of life, that has helped construct and reinforce this perspective. Many have not.
