You are talking about social media, the worst side to people - why would you put yourself through that when grieving.
People don't have a personal connection to the deceased, so lots of readers and commentators will use it as a way to justify why that can't possibly happen to them. Are you sure this isn't your motivation? For example:
There have been pictures of young people who sadly died of Covid where loads of people pile on to point out how obese they look and that's why they died.
Accidents will be the person's own fault "why were they up that mountain in these conditions," "they must have been driving too fast," "cyclists should know this is a dodgy corner...."
A women attacked by her husband should have seen the signs, left sooner, is to blame for not getting her kids out of the situation.
Suicide is a social contagion so it is irresponsible to mention that when talking about someone in loving terms, this is in line with Samaritans guidelines.
The main reason is, however, that it's none of your business.
