The aspect of "Its a wonderful life" brought upon a new movie called the "butterfly affect" Change ONE thing in life and that affects everything associated with it.
Do you feel you changed the world enough, that if you were not born the people you associate with would be affected? Sure they might not have gone to places only you invited them to, or not tried a certain food or drink. But do you think they would still be the same type of person, have the same job.
Also. Do you feel that the MAIN thread of destiny can not be avoided. For instance. Say you are 30 or 40. You find the job you love at age 40. You work 20 years doing other jobs, meeting other people in those jobs before you are 40.
Now you have the chance to go back in time and cut out all that wasted time, such as you get that job you love at age 20 instead of 40. So 20 years of meeting those people at those other jobs would not have happened.
Once again. FATE and DESTINY are disturbed. Destiny had it that you met your wife while working at one of those odd jobs before you turned 40.
Do you think FATE and DESTINY are real. Do you think DESTINY would still cause you to meet that WIFE of yours just in a different way.
For instance, you met your future wife because you both car pooled to that job that you NOW NEVER HAD. During car pooling you two got close and then started dating and got married.
Now you go back in time and never got that job but you are destined to meet that girl and marry her. Do you think FATE rearranges circumstances to cause you to meet that girl just in another environment?
Maybe her battery is dead and you help jump start her car and then you two end up dating.
Think Destiny is unavoidable but just different encounters. The MAIN THREAD OF LIFE being you are SUPPOSED TO MARRY this girl and all other instances in your life dont matter as long as you still meet and marry this girl?
