[Yes, there is a reason Zero is still in training to take over the position. Tact, he has none and is being forced to learn it on the job.]
I don't really see a problem with someone making an agreement to feed one as long as they are aware of the risks in doing so and agree with it.
The problem comes in trusting the vampire to disclose the appropriate information to the person agreeing to feed them. They often don't just see the need as long as their own desires are being met. I had an entire schools of girls transformed when I was actually there on campus because they were so enamored by this vampire's looks they just agreed to it.
We've seen this with Conrad. We can't do anything after the fact since they are so loyal.
Something needs to be done. There needs to be rules or something in place or there will be a repeat of the Winchester situation again.
It can't happen again. [Everyone is reacting after events happen. Zero feels a little alone in attempting to prevent everything all by himself. When something gets through his constant vigilance, it's himself he blames.]
