Why does milk not go bad when heated?

If heated milk is left sitting in the temperature danger zone, bacteria and other harmful pathogens multiply quickly. For pasteurisation to occur, the bacteria-infested milk needs to be kept at a higher temperature for an extended period of time, before it becomes safe to consume.

Does heating milk make it go bad?

There will be some nice friendly lactobacteria but maybe some unfriendly kinds too, so the sour spoiled milk won’t feel like yogurt, and it might make you sick. When you warm it up, as long as you get it above the pasteurization temperature (72C/161F) you’ll kill all the bacteria (good or bad).

Can you drink milk that was heated?

Unless you are already lactose intolerant or otherwise allergic to milk. Raising milk rapidly to a temperature above the danger zone (140 F / 60 C) is going to make it safer, not less safe. As a general rule, and assuming that there is no underlying medical condition, merely drinking heated milk will not make you sick.
