I'm thinking about stealing a pound of marijuana from the dispensary I work at.
Is this theft going to be a one-time heist?
I think this is a one-time thing.
Stealing is wrong no matter what, especially drugs. You are doing double the crime with theft and drug possession, is that really worth the jail time to you? A lot of people need this drug legally and medicinally, and you may cause some people to suffer from it.
But I'm going to donate the money I make from this heist to charity. It will do a lot of good in the end.
You are potentially hurting others by depriving them of it.   I see your reasons, but it is not a perfect crime
