The devil invented “sin”, a way to misguide our brains.
“Sin” is a DoS attack. It can be reformulated in another way (even if you don’t know what “DoS attack” is):
Sin is a too hard problem which overwhelms our brains and makes us unable to think properly about other problems.
So, we can conclude that sin is necessary, because that a problem is too hard does not make an allowance to skip it in the study. Sin needs to come into the world in order to be overcome (“solved”) organizing such a relationship between us and God which make it no problem anymore.
So the existence of sin and the devil are necessary. It is a part of the plan of God.
This is the explanation why all sufferings are necessary, as sufferings are just coming through too hard problems. But no problem is too hard to not be necessary to appear to be solved.
Why the devil and sin exist?
It is a paradox that the devil and sin exist in the world created by perfect, good God.
It is usually answered that it is because of pride. But the natural question would be: Why then pride exists?
The comprehensible answer is that every problem must be solved and to be solved a problem need to appear. So sin is necessary to appear in the universe.

Sin as a DoS attack for our brains designed by the devil.
This means that devil designed some “program” in our mind which disturbs other programs to work well. It is the reason why we cannot calculate like a computer.
Sin is not just a DoS attack but a DDoS attack that is the main problem lies not in our brains but in the attacker: (Eph. 6:12) “For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places.” This means that when the source of the attack is overcome, the problem with our brains remain minor and can be relatively easily solved.
(Heb. 2:5-8) “5 For he didn’t subject the world to come, of which we speak, to angels. 6 But one has somewhere testified, saying,
“What is man, that you think of him?
Or the son of man, that you care for him?
7 You made him a little lower than the angels.
You crowned him with glory and honor.
8 You have put all things in subjection under his feet.””
This mean that people who passed through sin and overcome (with God’s help) will be above angels. Why? I think the reason for this is the following: DoS attacks are nothing other than hard problems (for the brain). That is ability to stand against sin is a kind of problem which one should be able to solve. Probably some hard problems are similar to DoS attacks for the mind of one who tries to solve. Thus these who passed through sin and overcame are more clever than these who never passed through sin.
“For he who has died has been freed from sin.” (Rom. 6:7)
Our brain does not have enough computing power to overcome sin (which is a denial of service attack as a computer hacker would say). But when we die, our personality is transferred to a much more powerful computer run by God, so that the sin in us is overcome.

How to repent of sins (by a former maniacal killer)
In this short note I tell how to repent of your sins correctly. I strongly recommend to repent as described below.
Who knows how to repent of sins better than me, a former maniacal killer? Yes, I was a maniacal killer. I mean that I repeatedly attacked people with a knife with the purpose to kill and was unable to stop myself doing this because I had serious problems with my brain. Or, for example, once I said to a policemen “I am a maniacal killer. Give me a gun”; weirdly the policemen gave it to me; I tried to kill that policemen with a gun, but another policemen prevented me to do it.
