Bitch you better state your questions better if you want better answers . You are the reason llm's are still not a threat to some jobs.

If by bevelling badly you mean the formed loop is not uniform in "uniform mode" is because you have perpendicular with different orientations. to force an equidistant separation of loops use the extrude edge option that ignores the edge orientation and only uses its normal. This way you wont have pushed edge subdivisions.
If by badly you mean the error seen on your right its because you may have doubled vertices or collapsed faces.
But again ask your questions right.
