'Can anyone explain to me what the satisfaction is of seeing evil triumph?'
Evil's triumph is not for our satisfaction but our warning. Personally, I'm like you and want a hopeful ending I can aim at, but maybe the hope in tragedy is that you the reader didn't die or fail so hideously; we have a chance not to follow suit, and the trauma of suffering through the fictional failing is the shock we might need to keep us from the same fate.
Or it could be merely gratuitous drama and a matter of taste.

Both of these suggestions make a lot of sense. Thank you!
