I believe those college students,who died in their trip to M

I believe those college students,who died in their trip to Mount Everest,lacked a basic sense of responsibility for the society as well as for their families.
请问为什么用lacked ,在此句中做什么成分呢?
为什么不用lacking 应该是表示主动吧? 爱杉杉 1年前他留下的回答 已收到2个回答

这是谓语.老大...怎么能改成lacking呢. those college students, who died in their trip to Mount Everest, lacked a basic sense of responsibility for the society as well as for their families.
在这个句子中...I believe是主句...后面是宾语从句.其中who died in their trip to Mount Everest是those college students的定语从句..如果你还有不懂的那你QQ我吧493899533

整句句子结构是 I BELIEVE STH。
其中STH。 变成从句THAT（句中省略）还原为 STUDENTS LACK STH。
其中STUDENT有个从句/补充说明是怎么样的STUDENT-----DIED。
因为这里用DIED，所以LACK也要用过去时态。
如果用LACKING， 那么整句的谓语在哪里呢？
