Although Voodoo is a mixture of several different beliefs including Catholisism I could find nothing to indicate that an end-of-world belief is part of the religion.
If it is your voodoo doll (not one that belongs to someone else, or one you have found.) Then unraveling the voodoo doll is a way to undo or end the conjure, if there is one in place with the doll.
During your upkeep you put a pin counter on Voodoo Doll. If Voodoo Doll is untapped at the end of your turn it deal damage to it's controller equeal to the number of counters. You can pay double the amount of counters on Voodoo Doll, and tap Voodoo Doll to deal damage to target creature or player. Lets take the scenario that it is the beginning of your turn and there are currently 3 pin counters on Voodoo Doll. During your upkeep put a pin counter on Voodoo Doll (4 counters) At any time during your turn (when you can play an instant effect) you can pay 8 mana, tap Voodoo Doll and deal 4 damage to a target creature or player. If Voodoo Doll remains untapped at the end of your turn, you will take 4 damage and Voodoo Doll will be destroyed. You do not have to use the Voodoo Doll's ability, all you need is for Voodoo Doll to be tapped at the end of your turn. You could tap it with a fast effect, or use a spell to turn it into a creature and attack. There are a vast assortment of ways to prevent Voodoo Doll from dealing you damage. Personally i would suggest that you get a better 6 drop card. :) Good Luck (may you never be mana screwed)
By dropping a Guide Voodoo Doll in lava within hell. The dolls are dropped by Voodoo Demons, also found in hell.
