Legal consultation is urgent (please ask a professional lawyer to answer it, and make up points when you are ready)

According to your description, you can make the following judgments: 1. B told others that A was cheating others and violated A's personal privacy. Generally, the legal consequences of infringing on others' privacy rights include apologizing, eliminating the influence, restoring reputation and compensating for losses. But in your description, you can't see that A has any actual loss, just apologizing and eliminating the influence.

2. A entered the room in retaliation, and caused B to have certain personal injury consequences (the specific degree of injury can be determined according to the results of forensic identification), which belongs to intentional injury. If the forensic appraisal has the above-mentioned minor injury consequences, then A and his associates can constitute the corresponding intentional injury cases, and they will not only bear criminal responsibility, but also bear the civil compensation of B. This has nothing to do with whether B drinks, which means whether B drinks does not affect the nature of the case.

3. The police station's statement is not reasonable, but there is no serious violation of the law. Indeed, it is difficult for the police station to determine how to divide the responsibility before the results of the case investigation and the results of forensic identification of B's injury. Therefore, B's medical expenses should be paid in advance by himself or his family, and then B wakes up and asks why, so as to determine the attribution of responsibility. In view of this, there is nothing wrong with the police station's approach. Because the police station can inform his family that B has a family and his family should take care of B's previous responsibilities and medical expenses.

4. You can sue A at any time. But now B is in a coma and can be sued by B's dummy. It is suggested that it is best to do forensic identification of injuries immediately, so that the chances of winning the case are greater.

5. If A can constitute a criminal offence (that is, B's forensic appraisal result is minor injury), whether B wakes up and whether B sues A, the police have the right to detain A at any time according to the evidence, A's personal danger and the actual needs of investigating the case. However, it is up to the police to detain or arrest A.

6. Personally, I suggest that you can sue A for intentional injury while giving B a forensic appraisal, and let the rescued A escape.

7. You are quite right. If B becomes a vegetative or paraplegic person in the future, A will not only bear all civil compensation (specifically, local lawyers can be consulted), but also the intentional injury of A will lead to B's disability or vegetative state, which will be taken into account when sentencing.

article 234 of China's criminal law stipulates that "whoever intentionally hurts another person's body shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance." The second paragraph of this article also stipulates that "whoever commits the crime mentioned in the preceding paragraph and causes serious injuries shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years;" Whoever causes death or serious disability by particularly cruel means shall be sentenced to fixed-term imprisonment of not less than 1 years, life imprisonment or death. Where there are other provisions in this Law, such provisions shall prevail. "

8. It will not affect the compensation for B, nor will it affect the sentencing for A. B said that A's affair and A's beating B are two different things, which will not have a direct impact on each other.

This case is too big, involving compensation, and the crime is serious. It is recommended to find a local lawyer to represent the case, so as to get maximum protection.

I hope it helps you. Good luck.
