Sadly, it is infectious. That may be why traditions have tended to marginalize it when it happens. The evolutionary psychologist Steven Pinker discussed it in one of his books by noting that when a prominent suicide happens and is televised, there is a corresponding slight uptick of accidents in the area. He suggests that merely the suggestion of suicide can tip the balance in favor of reactionary recklessness for a tiny percentage in response to a bad event. It's important to have empathy for all those left behind, and it is sad for those who take their own life, but there is a danger in elevating their actions to being virtuous or somehow noble. The consequences are indeed quite selfish for all those left behind.
