What it means
かえって is an adverb meaning that the result was contrary to what was expected, often with the sense of “instead” or “all the more.” It commonly follows a contrasting or unfavorable condition and highlights an unexpected outcome. The outcome is often undesirable, but the form can also describe any result that goes in the opposite direction from what was intended or predicted.
Usage note
かえって usually implies a reversal of expectations, whereas むしろ can simply indicate a preference or comparison. Do not use かえって when there is no clear expected result or contrast.
