Depends. What war are you talking about? If it's WW1, then it's because everyone was stupid at the time and thought their enemies did it and one thing led to another.
Well that depends on who thoight the activities were positive
I don't know which specific context you refer to - the Han Chinese have conquered many people.
So I will provide one example - in Taiwan, the aboriginal people were required to have Chinese names in their passports until recently, which means that every person was forced to adopt a Chinese name, and often their original name was dropped, and (over generation) forgotten. This has changed how people self-identify: weakening their indigenous sense of identity.
