Is there any bad impact on my site from "Expired" or "Broken" Inbound links?
 

I just have a note that I have many back-links, unfortunately, a big ratio of them are now "expired", "webpage not available" or "broken".

So is there any cause to fear about them? I barely want to avoid them because I guess they all already rejected so no need to disavow them again.
What is your thought, please? I'm continuing on good thinking?

Yes a broken link is harmful for your webpage.

They make for a bad user experience – When users click on links and reach dead-end 404 errors, they get frustrated and may never return. They devalue your SEO efforts – Broken links restrict the flow of link equity throughout your site.
