I am going to guess that if they are committing suicide and not sacrificing their lives to save someone else then someone intending to commit suicide and also attempting to commit suicide is on the spiritual path of a downgrade and not an updgrade
Suicide is morally bad because it prevents you from the opportunity to live on to do something morally good
Sacrifice can be different than suicide
Sacrifice can involve risking your life to do good or avoid evil
Dr Ngandu is saying very Canadian politician type things
Is Doctor Ngandu a Canadian "medical" doctor?
There is a trolley it is going to either run over two people who are not murderers or a murderer with a gun who is trying to shoot those two people in order to murder them
You can not save both
If life is inherently valuable then the lives of the two people are more valuable than the life of the one murderer
This is a very utilitarian approach showing that what good or bad one would go on to do with their life if they do not die matters if life has inherent value
