From a philosophical perspective, judging who is more wronged between mother-in-law and daughter-in-law is not a proposition that can be quantified or objectively evaluated, because it involves personal emotions, subjective experience, and cultural background.
Each individual's feelings and definition of grievance are unique and influenced by personal values, expectations, experiences, and social circumstances.
In different cultures and social structures, the expectations and norms of the mother-in-law relationship are also different. Some cultures may emphasize the obedience and respect of the daughter-in-law to her mother-in-law, while in others, equality and independence may be encouraged. Therefore, who feels more aggrieved depends largely on the specific socio-cultural background and the individual's situation.
In addition, grievances are also related to an individual's psychological capacity, communication skills, and problem-solving skills. Some people may be more adaptable and resolve conflicts, while others may be more likely to feel aggrieved in the face of stress.
To sum up, philosophy does not provide simple answers to determine the grievances in the relationship between mother-in-law and daughter-in-law, but encourages us to understand the importance of individual differences, cultural influences, and personal emotions, and to seek understanding and harmony through dialogue and empathy in practical life.
