Could this community chime in and help me understand the seriousness of these 4 sins?

  1. porn

  2. pre-marital sex

  3. adultery

  4. emotional cheating

Obviously rape and murder and the 2 worst sins that a human can make but to me, porn is harmless and I'd compare it to being addicted to nicotine (smoking cigarettes). Sure it's unhealthy but God's not going to send you to hell because of porn, right?

Now onto emotional cheating -- I am married but I've had online affairs with some of my "chat friends" that I made in Asia (I live in America and I'm white). I love these girls because I have fallen in love with them because I'm not disciplined enough to stay loyal with my wife -- but I want this community's opinion on how bad is emotional cheating? (I never send nudes or engage in online sex -- I just pretend that the girls are my wives and they pretend I am their husband and we use lots of hug/kiss emojis and say "I love you" 20x per day)

Now pre-marital sex. I consider this about a "4" on a scale of 1-10 where porn is a 1 and murder or rape is a 10. Do other people agree with me that pre-marital sex is about a 4 here?

Lastly adultery -- (real sex with someone other than your wife). I consider this about an 8 because you could catch a sexual disease or get the woman pregnant -- or worst yet, the affair partner could murder your wife. (This actually happened in my town about 20 years ago and it made state-wide news).

Thank you in advance for answering my 4 questions about sin!

God bless!
