I do believe that the degree of evil required to plan and execute killing someone with ricin would be of such a massive degree that I cannot even conceive of such a person.
To die by ricin ,,,,well frankly?
You would die over a period of days (like Markov) not right away.
You would die in writhing agony,pain of such a measure I cannot comprehend or visualise.
Abdominal Cramps of such a degree that ......I can't even imagine
And they would get worse and and worse over a period of days and then you would die
Again I sometimes step back and just wonder how human beings can become so evil.
Sometimes you think about it, it is simply staggering
