Reason why we take births because we have unfulfilled desires we want to satiate those desires for which we want a body or a manifest form . Hence, we take births. The moment the " soul" enters the body (as it is going to be with that body for years together) it does anything when I say "anything" it can go to any extent of satiating those desires.That's why many people are unmindful about the consequences they act as per their wants Those who die with unfulfilled desires take the unmanifest form waiting for another chance to satiate those desires.
This does not confine to one birth or one birth-death cycle it goes on forever. A verse from Adi Shankaracharya says" Punarapi jananam Punarapi maranam" from the baja govindam song.
It is the soul which chooses the body . In other words, All a soul wants is a suitable body, which could be used as a medium so that it could achieve its destination.
Hence, do not curse the god for your plight.
Suppose, a man/woman dies before his/her stipulated time he/she will be roaming in this world as "spirits" once that stipulated period gets over, They will get away from this world.
The word "spirit" and "soul" are different. In Hindu culture, soul is addressed as "atma". whereas the Christian world consider "spirit"is confined to gross body.
Atma pervades everywhere. For example, you create a pot and there is a space outside the pot the "air" which is outside the pot also resides inside the pot. Once the pot is broken. the air which is inside the pot dissolves with the air outside the pot. And they become indistinguishable.
