If people didn't consuming animal products, were smoking, drinking,etc, we wouldn't need any hospitals.

There are no excuses of killing yourself, killing humans and killing other animals by promoting a lifestyle of animal products [see 1] and smoking.

This damaging lifestyle (including other destructive behaviors) is the reason of that there are hospitals.

But we should do our best to help them become less disconnected. The exclusion-lifestyle of saying "I don't care" at each meal consuming animal products is so disastrous both for the people and animals involved.
