I was always under the impression it was the killing of an animal that made animal products off-limits to [vegans].

From the Wikipedia article Veganism:

Vegans endeavor not to use or consume animal products of any kind. The most common reasons for becoming a vegan are human health, ethical commitment or moral conviction concerning animal rights or welfare, the environment, and spiritual or religious concerns. Of particular concern to many vegans are the practices involved in factory farming and animal testing, and the intensive use of land and other resources for animal farming.
