It depends on whether you mean bad for humans or bad for bacteria. If you mean bad for humans, mutations can make bacteria resistant to certain antibiotics and harder to kill. If you mean bad for bacteria, a mutation might cause a flaw in making some sort of vital protein the bacteria need to function; if, for example, the bacteria were unable to synthesize a certain nutrient without it and the nutrient was no longer in their medium for some reason, the entire colony could die.
You probably just mean bad for humans and good for bacteria, though, in which case random mutations can create tougher and more deadly bugs. It's as simple as that.
As known the genome contains 4 bases..these 4 bases in various orders (A+T , C+G) makes up our DNA which is responsible for protein synthesis in the end..
If by any reason a mutation occurs in one of the bases then is more likely that protein will not do its job therefore increasing the possibility of a disease.
Giving an example:
If a mutation occurs at the sequence that codes for insulin then the protein insulin will not function as it should... therefore when sugar is taken in when consuming a meal the organ responsible for secreting insulin will fail meaning that sugar levels in your blood will be high...and that's quite harmful for an organism.
Just a brief explanation how it works although if you want more solid examples and details please let me know :)

A large percentage of the mutations that occur result in death of the affected conceptus or the mutation has no particular favorable effect, thus it remains at a very low frequency in the population. Even recessive mutations with negative effects remain in the populationmutations at a low frequency...
Mutation is, of course, and absolutely amazing mechanism for change and one that generates diversity.
It causes your heart to implode on itself and the entire universe will go aerie.
The mutated cell might not do what it is supposed to. It could also be a cancer cell. And before you know it, the mutated cell has multiplied, so ther are billionns.
mutations in the reproductive cells of the body can be carried on to the next generation but mutations in the body cells won't alter the genes.
Gametic mutations occur in the cells of the gonads (which produce sperm and eggs) and may be inherited. There are two types of mutations that can occur in gamete cells: 1. Gene Mutations 2. Chromosomal Mutations
Mutations in reproductive cells (sperm/egg cell) can be caused by X rays and this can lead to birth defects.

No, not all mutations are passed on to children. Mutations can occur in the DNA of reproductive cells (eggs and sperm) and if they are present in those cells, they can be passed on to the next generation. However, most mutations occur in non-reproductive cells and are not passed on to offspring.
No not all mutations are bad there are good mutations and bad mutations
Since only gamete cells actually participate in the creation of a new organism, it is only the mutations in gamete cells which are inheritable; mutations in somatic cells are not inheritable.
mutations in the reproductive cells of the body can be carried on to the next generation but mutations in the body cells won't alter the genes.
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.
It depends on the age of the person. There are more mutations and defects in eggs as the woman ages. However, as men are constantly producing more sperm cells they will inevitably produce more cells that have mutations. The percentage of sperms cells that have mutations will increase as the man ages.
Mutations can be a source of genetic
cannot be passed on to offspring
No. But they are necessary for mutations to arise. Likewise, they are also necessary in order for mutations not to arise.

Some mutations cause cells to lose control over cell division
