This sounds patronizing. As adults, you make your choice and face the consequences. That you may have dependents does not reduce your moral responsibility one bit.
[edit]To be clear: I do not have dependents, but I also don't have an employer (who isn't me), and I do have people that depend on me. What I also have is a lot of experience in a lot of situations that are very much "gray" in terms of what less-experienced people seem to consider moral/ethical absolutes, which simply do not exist. That last part is what you don't understand but are likely to figure out as life teaches you the things your parents and teachers would like to but simply can't.[/edit]
Doing the right thing is sometimes difficult. That's not an excuse to do the wrong thing. Indiscriminately spamming hundreds of contacts is always the wrong thing.
