Yes, I do believe that if you make one insignificant decision that it could reflect horribly on your life, and the others around you. This actually takes make back to The Walking Dead (The number one show in America), three-fourths of the fifth season. three people, Glenn, Noah and Nicholas were going to a building to scavenge up materials for their group. When they were about to leave the zombies started to crowd them so they ended up getting stuck in spinning doors. Glenn and Noah on one side, and Nicholas on the other.
So what happens next is, Nicholas who is by himself on one side of the doors, escapes, leaving Glenn and Noah trapped on the other side of the doors. This action led to the death of Noah that shouldn’t
of happened. So when Noah died it gave Glenn time to escape. Nicholas, the guy who made the horrible decision, was trying to steal the vehicle they came with, and just leave. Well that didn’t work out for him, because Glenn the person who saw his friend die, came up from behind and just let it all go. He punched Nicholas a couple times in the face to knock him out.
When everyone returned to the camp, they were eventually going to spread the news of what had happened. Every single person was upset. They tried to communicate with Nicholas but he just wouldn’t cooperate with the group. He tried to help a couple times, but he didn’t always succeed. Later in the story Nicholas ended up committing suicide.
So when Nicholas made a horrible decision he didn’t know how to handle it properly. So that led to suicide, which became a very upsetting problem for all of the characters, especially Glenn.
