I framed a customer for damage I caused and then acted like I didn't know anything about it.
You're lying right? Why did you do that?
I didn't want to deal with the customer and I was afraid of getting in trouble with my boss.
You should take responsibility for your own actions. Letting someone else take the blame or putting it on them is wrong and immoral.
I'm not going to take the blame for it. They can't prove it was my fault.
It's not right to let them take the blame for this. They'll likely have to pay for damage you caused. Just consider how that must feel.
