She's gonna die either way. If you don't cut off her arm, she'll die from the infection. If you cut off her arm, she will still die probably from big blood lost, infection due to the walker blood on Clementine's axe or that scream will draw walkers on her.

As much as I wanna see her more and learn about her story, she's gonne die.
