On a scale of one to four, how dead is this guy?
It's a sad state of affairs when a beloved character dies; some fans won't even accept it as real, a predicament made all the more confusing because characters rarely stay dead. Because of this, fans love to speculate (morbidly) on the odds of a character coming Back from the Dead. The result is a kind of "Sorting Algorithm Of Deadness", where the circumstances, cause, genre, and reaction caused by a death are tallied up to see just how dead a character really is and the chances of their return.
To use the Algorithm, take each column's "Death Value", multiply it by the number of ticks in that column, add it all up and divide by the number of applicable rows.
To see calculations-of-permanence-of-death in action, see the Wild Mass Guess Sorting Algorithm of Deadness, where this table has been copied for clarity's sake. Also remember that the author may choose to subvert this trope and bring back a character no matter how 'dead' he should be, sometimes horrifically as an Undead or Reforged into a Minion. Of course, sometimes a low score on the algorithm is no guarantee that the character hasn't been Killed Off for Real.
See the Sorting Algorithm of Mortality to determine whether a character is likely to die in the first place.
