I'm not concerned with the end of the world. We each will have our own end of the world that is death.
If end of the world scenario is to happen during my lifetime I will probably be grateful to be able to witness it. Hey it's a big event.
What I am concerned with is the general demoralization of the world population. Not talking about strict morality but more about attitude and ideology towards living and being decent person.
More and more people( more even for the young) are becoming simply put selfish bastard idiot who worship their own ego and themselves. They will make the end of the world happen in their lifetime if their numbers keep increasing to majority of world's population. People now lie lightly, they deceive and are generally dishonest both in relationships and business. They are unashamed for the shameful and wrongful things they do and even proud of them. They are cruel, uncaring, ungrateful and rude towards other people. They live as if they know everything but in actuality they know nothing. They may even be religious but they honor mere rituals and people based on stature than honoring God and God's laws. They cheat on everything they do and proud of it. They take no advice and are disrespectful towards other people. They believe that right or wrong is relative and have no moral and religious principle. They blame other people for their own mistakes.
They are fools. Childish fools. Unpolished even rough people. Failing mankind I call them. A plague judging by their numbers. Trash that needs to be wiped out out of existence. Undeserving of time in this life and undeserving of other people time, friendship and affection. Undeveloped even regressed people. Predator of his fellow man. Mere animal in a human skin even worse than animal because they are mankind. A sad excuse for man's fallibility.
I am even convinced it's in their DNA not just a set of mind but a set of genes. A deteriorating mankind. Functional chaos. Defective. Defect.
