What's too good?????

While I am hunting for job, another book on my shelf was read and finished by me. This one written by Simon Mawer called ''The Gospel of Judas''.  There are a lot of discussion and objects, professions suspect they are propachy and gospel of Judas. For those who read Dan Brown's stories might interest to try like me. In my opinion, this did not impress me much.The story start exciting after middle of book.

What I'm thinking while I read this book is. A person who everyone complain he or she is bad, they could all give million and million of reasons why they hate or think these people is bad. Have anyone experience other complain that you are too good? I'm that person. In my life, there are 2 or 3 persons I know told that I am too good! Of course, they did not give any reason for me, what the word 'too good' mean?. So I have no idea how to improve or change myself. Some of my friend said they are just a bunch of people who felt bad when they spent time with me. They felt guilty when they talk to me. To be honest, be too bad or just bad, you can get some advice and improve yourselves (if you open and ready to do it), but for being too good, I'm not quite sure which direction or where I can get an advice.
