Buddhism Is non-theistic. Though, a Buddhist is open to a theist belief. Buddhism is a philosophy taught and practiced like a religion. 

The 7 noble path of enlightenment. And the state of Nirvana. Those are good propositions on the care for life. Virtuous ideals even taught/based on a natural level. In many cases you have Buddhist's who are pro-life, because killing unborn human life puts an un-necessary/cruel burden to the soul's experience of reincarnation. And thus should be avoided. So we have on the common plane of existence of what is good and right, most in common. 

Non-violence on the other hand is a faulty determination. For one, Buddhist's who lived in Japan under Hirohito didn't oppose the emperor's ruthless tyrant embarked upon destruction. A non-violent approach nonetheless, whereby the tyrant was successful unopposed. Even the U.S. was an isolationist/pacifist country at the beginning o World War II.

A Catholic response is to defend/protect one's neighbor.
