From a probability perspective, it's absolutely irrational. However that doesn't make your fear any less real to you.
After I went skydiving, the instructor came over to give me a pep talk in order to calm my nerves for what I was about to do—the most dangerous thing I may do all day—drive home. There are plenty of reasons to instinctually fear certain activities, but with rigorous preparation, inspection, and guidelines they can actually be safer than every day activities we grow complacent of.
Boeing's quality control issues have been known and talked about for years, and the initial MCAS problems with the MAX were the consequence of prioritizing certification and pilot training over a more robust redesign. But still, casualties per flight or per mile flown make even the least safe late model commercial airline remarkably reliable. Whenever an issue is discovered, they should ground the affected planes, investigate, resolve, and hopefully improve future quality control and maintenance guidelines.
So to answer your question, I would be comfortable to the extent that I wouldn't give the model of airplane a second thought and will buckle my seatbelt on the taxi ride to the airport next week for my flight. Airplane model unknown.
