How do other pathogens make the condition of AIDS fatal?

Lymphocytes are mainly concerned with providing immunity to our body. The causative agent of AIDS is HIV. When HIV enters our body, it multiplies using the genetic mechanism of lymphocytes. So the number of lymphocytes decreases considerably in our body. Thus the immune power of the body gets reduced. When various other pathogens enter our body, our body cannot provide proper immune response against these pathogens and we are likely to suffer from various other diseases so it can make the condition of AIDS fatal.
