TU-ing a bereavement post does not mean the thumber likes the loss of a loved one or is glad the loved one is gone. It means the thumber is showing solidarity with the one who lost someone.

Everybody takes grief differently but you could express your condolences in a better way i.e. a private message.

The idea of seeing a stream of crying emojis, awkward condolences, or, worse, “likes,” roll in from hundreds of friends, acquaintances, joe public may feel, well, intolerable.

Then you also have criminals who mock their victims or in this case the victim's grieving family on social media.
