Mixed feelings

I presume that as a leader, you will be expected to do some things that you may find distasteful or unpleasant - like reprimanding someone for poor choice of action, telling people some bad news, or even letting an employee go. This is probably one of the main reasons I don't pine after an administrators job; I don't want to have to do these things. Not that they don't have to be done, but I don't want to be the person to do it.

So it is with mixed feeling that I note the replacement of our prior instructor. I know that I was part of the wave that got him replaced and I am trying to not feel guilty. I KNOW that he didn't perform his job as expected, that he did not offer the leadership required, and that the entire class suffered because of his unavailability. I also know how upset I was when I had questions or concerns with no feedback from any authoritative source to help me get straightened out. I know that he did not fulfill his responsibilities as the instructor to actually instruct. 

Yet I still find myself asking questions like - Could I have been more diligent in trying to contact him? Could I have been more understanding of technical difficulties? Could I have continued to suffer through without his guidance and leadership? Would any of this have made a difference? Was I too intolerant of the situation? 

Even though the answer to these questions reaffirm that the correct decision was made, I still feel partly responsible, and continue to question: was I right?
