Anybody who hasn't opted in to be an organ donor and/or donated to science is a selfish piece-of-shit. If you're gone, why would you not want to be used any way possible to help others live? Anything remaining of you can still be buried or cremated if that is what you/your loved ones want.
I mentioned this story before, but when I was at Texas State, there was a body farm just miles down a back road from me. There were dozens of bodies scattered around the acreage, some purposely hidden with foliage for police investigation research purposes, that the deceased had opted in for science. I always thought that was noble of them.
Funerals/funeral homes are a money grab. My mom's best friend's parents owned multiple funeral homes, and they made a small fortune with them during their time. As others have said, I don't want people's last visuals of me to be a wax figure in a casket with them crying over me. I don't want people spending their time in sorrow at calling hours. I'd rather you take that time to be with your family, volunteer to help somebody, etc. Grieve me in your own time and be there for others. Use me as an organ donor/science, cremate the rest, and put me with other family who has been cremated.
Disagree, and Jesus, you're really an inconsiderate and unthoughtful person.
It's out of honor and respect for the deceased. Even if you didn't know the family, if you cared about the deceased, you would want their loved ones (family and other friends) to know how much he/she was loved and respected. That is part of healing for the family of the deceased, and I assure you, the deceased would want that of you for the sake of their family.
When my brother passed, my mother and I didn't have a service. We were too emotionally distraught to have one in a normal timeframe, but his friends had a gathering in memory. Over 2.5 years later, I have kept his phone on, because he still gets calls/texts from old friends/business associates who are not aware and are reaching out to him to catch-up. Being the one to have to break the news to each old friend is the same nightmare over-and-over, but hearing their stories and condolences does help.
