Do stupid mistakes warrant retries?

[treblesum81]

Simple enough question I think, which means there are probably endless points of view, but I'm curious because I find myself making lots of stupid mistakes and then lots of retries. So, if you make a really stupid mistake in the process of conducting an attack, ie forget to update the bearing to target so the fish run wildly in the wrong direction, do you allow yourself to return to a previous save to retry the attack? Or do you just suck it up and move on?

Thanks
