I woke up this morning and saw I had 1 karma and also three new badges, but what I don't understand is why one of the badges I got is showing me as "Karma Bad." You can see it in the image below.

Secondly, I want to ask the function of the [+ karma] and [-karma] on people's profiles. I tapped on the + karma on someone's profile this morning, hoping it would bring up any further message or option, but it did not, and at a point I also thought my own karma would disappear and go to the person, but it did not.
My question is: what is the function of those keys in the image below? Again, if I award karma to a user, will it reduce my own earned karma?

I am unable to find an answer to the question in any other thread, so I decided to ask.
