This might not be the best approach to take with the death of people, but it seems like a good approach for when a loved pet dies. I have noticed this topic came up a few times on this forum, so I thought it might be appropriate.
I found this on reddit.
"I woke up to my mother telling me that I had to put my dog of 6 years to sleep because he had a nasty tumor that was threatening his life. I had one hour before the vet, and needless to say I was in shambles.
What the vet said though made me feel really good: "I know exactly where you've been son, and let me tell you a little bit about the difference between nature and science. In the wild, dogs would be killed off our abandoned by their pack by the slightest showing of weakness, so they keep quiet and suffer to themselves. You will never know how much an animal is hurting because mostly they will keep it in. Now I'm not sure what you believe, but I want to give credit to science for developing a serum that will not only peacefully put him to sleep, but he will quietly ease into the void of death, as opposed to suffering for countless days and hours before his heart stops."
Maybe I'm just delusional and shouldn't post this here, but seriously fuck God haha. Science makes death easier for everyone involved whereas that pussy in the sky gets off by making death involve suffering."
