Well crap!! Been eating raw almonds for years. Never ever had a problem. No drain bamage either! :)
If you have been eating raw almonds, and they have not been processed then they are sweet almonds. In the United States raw bitter almonds are required to be heat processed. I don’t think you need to “cook” them but you have to heat them. Otherwise a few handfuls of raw bitter almonds could kill you.
If you really want to die fast, then eat raw castor beans. They contain ricin.
