"I should suffer"

"Why?"

"Because I deserve it" is not specific! One can't give a valid reason one should suffer, be alone, or miserable because there's no such reason. Certain Gods believed they had to suffer for mankind but, as far as I know, you and I are not certain Gods? If one gets specific as in "I deserve to be alone because I was not a good friend to Susie" then that just says Susie might not want to be your friend, not that you deserve to be alone or that you'll treat Sally the same. We cannot be specific about general/galactic conditions, only general/galactic and they're as unsatisfying to intelligent people such as ourselves as the conditions.

Not only that, but they're impossible! "I should be miserable"; you can't be miserable all the time, even if you try (anymore than you can be happy all the time) because you can't control what is going to happen around you that you will have to respond to; you going to be miserable if you get a good grade on a school test? A promotion? A job you want? A new friend/lover? On a sunny day after a week of rain? When it cools after 100 degree days? When the lights and AC come back on after a power outage?
