He said he did not want others to suffer the same anguish and suffering.
He also cited the story of Christian Rossiter, who was a quadriplegic who had to be had to be fed using a tube to his stomach and talk through a tracheotomy, a hole in his neck.
Trapped inside a barely functioning body, Mr Rossiter asked to die and in August, the Supreme Court granted his wish to refuse medical treatment, which included removing his stomach tube and starving to death.
He died a month later following a chest infection.
Mr Chapple said: "I believe our society is sufficiently compassionate that it can recognise that for some people, the pain and suffering is so great and so prolonged, that death is the only way out.
"Surely we can do better for those people than a death by starvation or dehydration, or some other way that the person conjures up.
"Surely we can offer a controlled, gentle, peaceful and quick death. This Bill will provide that option."
The other reasons he gave were autonomy, legal clarity and statistics.
"In August 2009, Westpoll declared that 79% of Western Australians support voluntary euthanasia," Mr Chapple said.
"In October 2009, Newspoll declared that 87% of Western Australians support voluntary euthanasia. Regional members take note: that figure increases to 92% in regional WA."
The bill will now be debated in front of a full parliamentary sitting in the spring session, around September or October.
