Seduction is indeed human, and everyone who is sexually active does it to some degree, whether or not they are doing so consciously.

Whether it is "good" or "bad" depends entirely upon intent; illegal action of many kinds requires a finding of intent.

Anyone, male or female, who attempts to seduce someone else for nefarious purposes is in the wrong, and is doing something both amoral and unethical.

But there is a lot more to seduction than that. Seduction, in fact, goes on in pretty much every bedroom among consenting adults at one time or another; what man, or woman, has never tried to seduce their lover, especially early in the relationship?

Is seduction still "bad" if both parties are totally into it, and enjoying the process?

As for hypnosis and NLP, as you stated, neither can force anyone into doing something against their will. Many hypnotists have tried, including in government studies, and it simply doesn't work.

Having said that, people hypnotize themselves on a regular basis, and anyone acting in trance is capable of making some pretty detrimental decisions that can cause harm to their own basic welfare.

Men and women who choose to keep going back to a harmful relationship often fall into this category. No hypnotist needed.
