And why or why not?

On homework, only when you really need the grades. For tests, I never like to cheat but have done it a couple of times to save my grade. But I don't make it a habit to cheat. On a significant other, it's not okay to cheat. If you say you're monogamous, you stay that way. If you both say you're seeing other people (multiple relationships) or something like that, it's not cheating. Not my taste though. Games, I only cheat when the other person is.

Number one, I would NEVER honestly form another relationship on par with the one with my girlfriend. She deserved better than that, and if I fell from grace like that I would not expect her to forgive me.

Homework, yes, definitely okay. You know why? In high school, it's not so bad. In college, professors, can screw you right and left with things, and have no mercy. So communicating with friends is important, like copying homework. That's fine- but I wouldn't stare from someone else's test.

Games- no. I don't like cheating in what is supposed to be a form of entertainment. I like honest wins.

i cant and wont cheat on my girlfriend, she deserves my trust.

i will skim the books a bit to get a right anwser but i will always atleast know how to arrive at the right anwser before i just skip the whole learning phase. tests and more serious stuff i wont cheat - i dont even peak in the washroom.

as for games im a notorious cheater since i love to get perfect master files. i will often play through the game once to enjoy the freedom of discovery, then i will go get a guide and check out the stuff id missed.

Any oppertunity that you get.

What is the harm in cheating on a husband, wife, boyfriend, girlfriend, etc. if they never find out?

I find it immoral for the fact that you say you're committed to someone, yet you go behind their back to f*ck someone else. Even if it's behind their back, there can be some consequences if something goes wrong. Say you get the "mistress" pregnant. What're you going to do then. Mistress will probably want you to help raise it. If you're already married and have small kids of your own, this is going to be a tough situation. So what's the harm? If they find out, well, it's obvious. If they don't, there can still be consequences you may not want to face.

When someone keeps flanking you from a top of a cliff without every leaving that spot. That is when you deliberately break the "no explosives" rule you set for each other.

Homework - when you know the data you are learning isn't something that is going to be on a test or ever used later in life (but theoretically, never)

Girlfriends - Never.

Games - If you've beaten it once before without cheating.

Hey is it cheating if you play a survival horror game, go through a lot of ammo and health but see all the obstacles ahead of you and then go back to the last saved game and play a 'clean' run to the next save point?

Also what about in an RPG if you intentionally play a couple rounds to learn what class, attacks, weaknesses a boss has and then quit without trying to win so that you can better prepare for the battle?

I wouldn't call that cheating as much as just being cheap, if that makes sense.

It's being lame, imo. FIGHT THE BOSS WITH WHAT YOU HAVE!
