[Looper] Why do they send old loopers back to in to be killed by their younger self?

Why are loopers sent back in time 30 years to be killed by themselves? Why even send them back at all? What possible reason would the criminal organizations have for letting the old loopers walk around free for 30 years and then randomly send them back to die instead of just letting them stay retired and die of old age?

1. The loopers might know things they shouldn't. Simpler to kill them.
2. It's amusingly poetic and ties a neat little paradox bow on their lives. Crime families enjoy that.
3. The boss is kind of a lunatic.
