No, there is a level of competency where once you make mistakes below that, firing is the right move.

If a surgeon keeps killing patients because he keeps forgetting to wash his hands, then he needs to be fired.

If a developer skips all company policies and deploys directly to production without a good reason, then he needs to be fired.

There are reasonable mistakes, then there are errors resulting from wreckless actions indicative of a larger problem with the person's view towards their work.
