2. Radiation
If there is a really slow and boring death that is the one caused by radiation that’s up next on our list of most painful worst ways to die. Maybe the word boring is not a perfectly chosen for this situation, but people who died from the high level of the radiation were literally wishing to die as soon as possible. Depending on the level of radiation and the durability of the exposure, a person can have deep and awful burns on the skin and even in body organs, can be poisoned and have hallucinations. During that time, they feel severe pain.
