I agree magic shouldn't be used for every matter in ones life, but I do believe if you need a helping hand then it should be used if you believe it can help.
I'll give you an example, when I first started working in security I was 17 and would search people as they entered the clubs. A promotion came up that I was told I deserved but someone else wanted their relative to get the position and held a lot of sway in the company, his relative had never worked security before, so I did a spell on the boss to use clarity in making his decision for the position rather than a spell to give me the job. If he had of bowed down to pressure it would have risked the customers because I had the experience in searching, whereas this person didn't, so to me my spell was ethical.
It worked because he gave me the position after basically agreeing to give it to my colleagues relative, because of my age it was a risk but it worked out excellent for us both.
