Unknown to him, Alex had already turned into a prepper. A group of people that was prevalent in his previous life.
Every one of his actions was to prepare himself to survive the bleak future. He knew something horrible was about to happen. And this was his method of coping with the situation.
But unlike the preppers in his past life, Alex was different. He was not just trying to ensure his survival. He was also trying to ensure the survivability of everyone. His goal differentiated him from the others.
Only the insane would try to save the entire world. And in conclusion, Alex was insane.
Even though his words often make him seem like a pessimistic bum that wants to see the world burn, his actions often told otherwise.
A person should be judged by their action. Not by the sweet words he had spoken. A politician is capable of lying through his teeth. But his actions will always show his real self.
