First, welcome to the community and we hope you will have a long and nice stay and make a lots of friends.
For your questions.
I think it's nice when you recieve Tarot as a gift, but you do the same job with a deck that is bought.
In my opinion, it is not the deck that is the important thing, but the reader.
In order to give good readings, you must have a great understanding of people and a very good intiuation.
The cards can be read in several ways and since you felt guilty you might have beleievd you did "dark magic"
Sorry to say, but it can be used for "dark magic".
B U T that is the choise of the reader, it's he/she that use the cards the way they self see fit.
If you start out looking for the "negative" you find it...if you start looking for the posetive...you find it.
So if Tarot is used the right way it can be a tool to enlighten peoples mind and give them new goals.
So if you use it for the light....don't be afraid of it....if you use it for the dark....burn them
