Yes, still he suffered a great deal before that from cancer of the jaw. I read in the end his breath smelled so bad even his most beloved and loyal dog wouldn't come near him anymore.
Ironically he wrote this about suicide:
"So immense is the ego's self-love, which we have come to recognize as the primal state from which instinctual life proceeds, and so vast is the amount of narcissistic libido which we see liberated in the fear that emerges at a threat to life, that we cannot conceive how that ego can consent to its own destruction."

I guess he found out, didn't he?
I abhor people who think they have the right to dictate their own moral views to others and force them to live and die a certain way. Freud was instrumental in the emergence of psychiatry which in my mind is one of the greatest threats to freedom and the rule of law ever devised. Not to mention it's prety much quackery just like Freud's completely unscientific 'theories'.
