Seems pretty clear that morality is not your choice. Pretty sad, because even here on earth you will not find fullfillment. -me-

What does this have to do with morality?

Everything. That you think that acting in a moral way, and living eternally in a moral state would be boring shows that you think immorality = fun.

First, you don't know me personally so I don't know how you can be so sure that I am an immoral person. I try to be as moral as possible and I assume the same applies to you.
However I don't claim to know that you cling to an immoral lifestyle.

Further I don't think that immorality=fun. But I doubt that an eternal life can be interesting for ever, and whatever you do, be it absolutely moral or totally immoral doesn't matter - at some point your existence becomes boring.
Of course I can imagine that this doesn't happen but only as it can happen that a person with a certain kind of brain damage can watch the same movie again and again as if it were the first time. But this isn't exactly what I had in mind.

In this sense I have to agree with Mencken who said that "no show, however good, could conceivably be good forever".
