But question is, do the victims find it as funny as the trolls themselves?

This story of how Facebook troll tormented grieving friends and family on tribute pages to Natasha Macbryne certainty did not find it funny.

The cruelty of Sean Duffy's actions highlight how hurtful and disgusting Facebook trolling can be, to mock the death of a young girl shows inhumanity in his life to show no respect or consideration to those grieving.
