Entropy (the tendency to decay, the inevitability of death) is dominant in this mortal world and the known universe.
Entropy is a type of evil: because so long as entropy is, then whatever is Good will decay, will die.
Thus decay and death are an evil.
And yet, since Jesus Christ; death is also potentially a path to everlasting life in Heaven... In other words, to a mode of existence without entropy, without decay or death.
(Because all evil - including entropy - has been left-behind.)
Indeed, death is the only path to eternal, sinless life.
Therefore; while death is an evil, for a Christian death of the mortal body it is also the death of evil: the one and only path to Good.
Exactly such is the Christian's experience of the fact of death:
For us; death is a terrible and unavoidable evil.
And death is our necessary path to an otherwise unattainable everlasting, wholly-Good, way of being.
