There are 3 things that can be harmful if it reduces the organisms for survival and reproduction. The three things are changes in DNA, changes in phenotype and mutation .
Most animals are not born with harmful inherited traits because they are not advantageous to survival. Organisms are created to reproduce and survive.
Asexual reproduction does not allow for bio-diversity. Therefore if a disease comes along and effects one of them, the entire species will be very susceptible to the same disease, and entire species can be wiped out

Organisms and insects help to keep soil healthy. They help break down harmful elements and excrete substances to improve the soil.
The condition is called as infective disease.
Chemical resistance

There are harmful to all organisms, but some bacteria are helpful in many ways.
drugs!
Some of them are, however, there are many microscopic organisms that are not harmful, some of which you could not survive without.
harmful micro organisms can make animals sick but not harmful micro organisms can help them.
Mutation can be caused by many factors (birth defects, exposure, etc.). It is often times harmful (in birth defects: person with three #23 chromosomes; in exposure: a person handling uranium). (sometimes exposure can often kill off cancer [but then again so can Chemo])
Yes & No. It depends on what stage the cancer is on e.g. the 1st or 2nd stage is not that dangerous or harmful, but if it is the 3rd stage or above that then they are less chances of survival. Im not really sure about the 3rd stage but above that, YES there is most probably less survival
Always harmful to their host
agree
Kills bacteria and harmful organisms.
Transgenic organisms are good because they are engineered to have the characteristics of another organism for its benefit. This increases resistance to harm and other factors in such organisms. As for harmful reasons, I cannot think of any.
