Need help about the meaning of V+ するからいけないのよ (V+suru kara ikenai no yo)


When reading , I met with this grammar , and not sure about its meaning. Much
thanks if anyone can help me understand correctly o/

Example: **変に意識するからいけないのよ**

I have 2 guesses :

1/You shouldn't have weird/strange thoughts about it.

and

2/Do not have weird/strange thoughts about it !




The first translation sounds perfect for me. It must be an advice or criticism
thrown toward someone who looks suspicious.

Translating the seconds one back, it becomes like 変なこと考えないで！, which could
never be an intention of the example you provide.
