I have "Considered" stealing from my employer several times. When I was 15 I was a refugee and worked in a Radio-Shack-like store in Croatia. We built PCs in back and sold them in the front. The front and back were separated by a curtain, and highest value items (ram sticks) happened to be stashed on the shelf on the side of the entrance. I realized it would take literally 5 seconds for a customer to reach through the curtain and grab them. That got me thinking on whether as an insider I would have higher or lower risk than a random customer. How could I reduce the risk? What's a simple, non-overly-elaborate method that would let me accomplish this? So I did spend some time considering this problem space (and then next day suggested to my boss to move the RAM further inside:)
Similarly with suicide. Everybody's life is hard and has ups and downs. I've "considered" suicide in several different ways many times in my life, sometimes at "obvious" times of hardship, otherwise at simply slow, boring times. I'm largely a cheerful optimistic person FWIW, but I find everything interesting even fascinating, including that particular life (ending) choice.
Talking to couple of my closest oldest friends, who are most similar to me, they have few mental taboos. But talking to most other people, at least as far as they're willing to be honest with me and/or themselves, they have never considered SO MANY topics, virtually regardless of how light or heavy we define the word.
