Is it a good idea?

Is it a bad idea that I want to Travel to the lower frequencies with all the negative spirit, The reason I want to do this, To gain more knowledge on what causes them to be who they are? To see see more into what they are like? To help them. etc..

I read in this book , to visit the lower astral realms will make one bad , mad or dead , I dont think this is such a good idea .

But you don't seriously believe everything you read do you?

People arbitrarily label stuff that makes them feel bad "lower"...

It's consciousness, there is no here or there, no upper or lower.  Only subjective interpretations based upon biased values of the experiencer.

Visit where ever you're able to... It's all valuable experience.

 There are "lessons' to be found in all experiences!

Lol, it sounds kind of fun when you put it that way.

In the Shamanic views, there are upper and lower realms.
One is neither better or worse than the other, just different
beings in different places.
If you go looking for negative energies, you will find them...
and you may get more than you bargain for !
But I'm sure you will learn from it...

Intention is a powerful thing. If there was a danger before, my feeling is that your intention to visit these places for the good of others will have a lot to do with the outcomes you experience.

Exactly. And every 'place' offers some learning opportunities, although it is natural (at least to me) to 'like' the higher (lighter, less denser) places more. 
Also, low(er planes) and high(er planes) are metaphors used in almost every description of non-physical reality, Eastern, Shamanic, even R. Monroe counted his Focus Levels from 'down' to 'up high' (C1 = physical to F27 and far beyond that). They are not meant by most who use them to be literally interpreted in physical terms. Metaphors are effective elements of language by which we communicate with effectively, so we know what we are talking about and that it could be, at least approximately, the 'same thing'.
