Should I replace this small piece of brake line?

[xdarkxfirex]

I had worked on the master cylinder many times, and pushed it in and out with the lines attached to see if there is a leak. I had a stripped nut and replaced it by cutting the flare and using another nut I had laying around. I am just worried about the line near the back connecting to the mc. I moved it so many times, and when it was replaced, had a small kink from bending but no leaks. It moves from the bracket being moved. Should I replace it or leave it alone? It has been fine for the past two weeks.
