When you see an attractive girl,for example...and you are a teenager full of hormones...the first natural inclination is to try and have her.
This is the Yetzer Hara.
The second inclination is to bless her and keep your hands off of her since she is so beautiful and rare. This is the Yetzer Tov.
Ah, it appears that whoever taught you about Yetzer Hara and Yetzer Hatov simply misrepresented them or you simply misunderstood what was taught.
They are totally unrelated to any demons or demonic forces or outside forces. Nor are your examples related. It is only the outcome that determines whether something is Yetzer Hara and Yetzer Hatov. In the first example if the boy desires the girl and the girls desires the boy and they become lovers then it is Yetzer Hatov,
They gave each other a pledge.
(Unheard of, absurd.)
You gave each other a pledge?
(Unthinkable.)
Where do you think you are?
In Moscow? In Paris? Where do think they are? America?
And what do you think you're doing?
You stitcher, you nothing! Who do think you are? King Solomon?
This isn't the way it's done, not here, not now.
Some things I will not, I cannot, allow.
Tradition!
Marriages must be arranged by the papa.
This should never changed!
One little time you pull out a prop, and where does it stop?
Where does it stop?
Where does it stop?
Now if the boy desires the girl but the girl thinks the boy is a bupkes and yet he forces himself on her then it is Yetzer Hara unless of course the girl is a shlimizel in which case it is just normal.
It is not God or Demons that are involved in Yetzer Hara or Yetzer Hatov, no warfare, no fight and actually no firm list of what is Yetzer Hara or Yetzer Hatov. Any differences between them often are subtle and shifting and totally internal to the individuals and the situation and dependent on outcomes.
Anyone so limited that they can only spell a word one way is severely handicapped!
