People will change as a result of the circumstances that surround them. We all do, and we all should, as our priorities change.
If you are the same person now that you were 10 years ago, ask yourself, why? Are you still learning and growing? Do you only care for yourself or do you have others to care for now? It’s OK that people change over the years. If they didn’t, that wouldn’t be normal. I would hope that your beliefs from when you’re 18 years old and not allowed to legally drink change when you’re a 30-year old with kids, a 50-year old starting to think about retirement, or a 75-year old thinking about the future of your grandkids when you’re gone.
Your core values, morals, and ethics should be constant. But don’t demonize a person for changing their mind on specific topics. As they are presented more information, they should be receptive to changing their thoughts based on the new information they’ve received.
