The obvious sins were mentioned, of course, but there's so much more than that - like the utterly unforgivable sin of stank food at the office. Got people over here trying to do spreadsheets with one hand because we're covering our noses with the other. Spreadsheets are a two-handed activity, Brenda. We don't care if the fish was on sale.

Here are some of the other more popular responses, edited for language or clarity if needed.

This Math Joke

Sin(1/(4-x))

... That sin function has no solution at x=4. It's an unFOURgiveable SIN.

Elder Abuse

Abusing the elderly. I went to college for social work and they showed us a short video about people who mug the elderly, as in come up to them and just steal their wallet or purse, knowing that they can't do anything about it. In the next section it showed how some can be abused at home, locked into their room and let outside twice or three times a day for food and toilet, but otherwise just locked away in a small room just big enough to fit a bed so they're out of the way.

I was horrified, how can you treat someone that raised you or your spouse that way?! It made me sick.

It's All Theft

There is a quote from Kite runner about sin that ill remember forever.

There is only one sin, only one. And that is theft. Every other sin is a variation of theft. When you kill a man, you steal a life... you steal his wife's right to a husband, rob his children of a father. When you tell a lie, you steal someone's right to the truth. When you cheat, you steal the right to fairness... there is no act more wretched than stealing.

False Accusations

False rape accusations. Rape is horrific, and false accusations don't happen often - but when they do it's a nightmare. False rape allegations are a 2 way sin. 1: You destroy the life of the falsely accused. 2: You mitigate and minimize real rape.

Office Food

Microwaving fish in the office microwave, then proceeding to eat it in an open plan office. Pungent food in enclosed spaces with other people is an absolute sin. As someone who works in an open plan office near the kitchen I get the blunt force trauma of smells.

Gym Sins

There are so many gym sins

Curling in the squat rack

Hogging dumbbells for your drop sets.

Using the flat bench for anything other than bench pressing, especially if there are only 2-3b. Especially ESPECIALLY on Mondays.

Working out with a group of 3+.

Using another free piece of equipment/bench to set up your phone to record yourself.

Just walking in and asking how many more sets someone has who just got there because they are bigger and more important so their time is more valuable.

Bringing a personal bluetooth speaker with you.

Livestreaming your stretches in front of mirrors.

Slamming the cable machine plates.

Wearing those string tank tops that barely cover your torso with a dress code that says shirts must be worn.

Doing HIIT in between your sets and sprinting from one end of the gym to the other and getting pissed because people are in your way.

Perving on female gym goers.

Unnecessarily dropping weights on the floor. There only are very few exercises where dropping them is needed. Otherwise it will damage the floor and the equipment and can be harmful to your health.

Not using towels and/or wiping of your sweat of benches.

Not allowing anyone to use the machine in between your sets, especially if you do circle training.

Not removing weights after you finished your sets and also not putting dumbbells back on the rack.
