The important thing is to die in the state of grace. While those who die early would therefore not have had the opportunity to amass a great deal of wounds/debt from sin, likewise their opportunity to bring more glory to God is also diminished.
God receives glory from our lives when well lived. That is part of the reason we revere saints; they bring great glory to God therefore killing someone prematurely (and at anytime) is robbing God of the glory that could come from that person's life so if you die young you are not better off. You have less to bring to God in that respect, for all our victories will bring us from glory to glory.
There really isn't a formal church declaration on this matter but you can figure it out from a little reasoning.
