He was talking as opposed to suicide that is referred to in a gemara - where people commit suicide to show Hashem that they can also be in control of life/death. He said that doesn't happen today.
That is the accepted Halacha today. In Japan where they commit suicide Beshita - not from depression, ain lo chelek leolam haba.
Someone that commits bec. of depression is considerd an "o'nes" and gets a levaya etc.
