Yes, of course. Definitely it is worth installing since it will stop further corruption. It is just that you may already have some filesystem corruption so some crashes may remain. One example is previous installation of something over wi-fi that may cause corrupted binaries being saved while they are installed. Same applies to various configuration files saved by system or applications, see this.
However it is possible that your system is still in good shape since most errors are only in RAM and there is high probability they bring system or application down before anything is saved permanently.

Reflash only if you have problems or want to start from clean system.
