Deep down does the narcissist have regret for the pain he causes his victims?
I don't think they do. But I think they have moments of clarity where they realise what they had and that's when they come back. But once they get over that they get meaner as they are pissed off for feeling any vulnerabilities.
AnswerI once asked my ex-N how he felt about all the women he had hurt in the past. He 'literally' said verbatum and with an arrogant, careless tone, "I don't care." I had just learned of what his pastors wife called "a trail of wreckage" of broken hearted women behind him. A few weeks later I asked the exact same question and he said "I have compassion for them". It sounded like pity. I believe the first answer was the real truth. The second was a clean-up of his first - even though it wasn't much of a clean-up. I searched for remorse and found none. I must assume he now has the same attitude about me now that we are no in each others lives. Any contact since we broke up has always been of a blaming nature. He was emotionally, verbally and physically abusive yet still blames me for the demise of our relationship. He never accused me of any abuse (because I never did) and only said it was "the most fulfilling relationship of his life and he always felt great compassion and love from me". Still, he blames and shows no evidence of remorse. Although I believe he 'regrets' losing me and knows he could have done things differently to prevent me from leaving, but couldn't control/change himself enough to do so.I would love to know if anyone knows of any N's who have truly been remorseful.

Why is oxygen poor blood pumped to the lungs?
The lungs take in oxygen, this oxygen travels down to the alveoli (thin, permeable sacs), which are covered in blood vessels, and the oxygen travels into the blood due to a pressure difference and CO2 goes from the blood to the lungs to be exhaled. The body needs that oxygen for almost every system in the body.

Superficial vein is a term used to describe a vein that is close to the surface of the body. It is used to differentiate veins that are close to the surface from veins that are far from the surface, known as deep veins.
