Don't commit seppuku. That's an overreaction. Suicide should never be an option until you have exhausted literally everything else, and "everything else" is such an immense field that really, suicide never makes sense.
You have a choice. Either you keep what you're doing any try to find meaning in it, or you change your life and do something else. If you're not satisfied and have something better to move on to, then do that.
This is one situation where being a hacker is not recommended.
I had to do a search for this word when I read the post and didnt quite get what a moral suicide means.
Apparently, a knife to the gut, then slicing across is very painful. To end the pain, there's someone else that beheads you after you do that. Imagine if that person didn't make a clean cut, and went into your shoulder instead. Now, not only are you suffering a slow and painful death, you have blades sticking out of you.
