It seems there might be a typo or a misunderstanding in your question. As it stands, the term "violet type of guy" doesn't have a commonly understood meaning. If you meant to ask about identifying whether a guy is violent or exhibits violent tendencies, then that's a different matter.
Identifying potentially violent behavior in a person is crucial for one's safety and the safety of others. Here are some warning signs to look out for:
Aggressive Behavior: Frequent displays of anger, rage, or aggression toward others, whether verbally or physically.
History of Violence: If the person has a documented history of violent actions or has been involved in fights or assaults in the past.
Controlling Attitude: A person who exhibits controlling behavior, tries to dominate or manipulate others, and disregards their boundaries may be prone to violence.
Threats of Violence: Making frequent threats of harm, even if they claim they are not serious or are joking.
Blaming Others: A tendency to blame others or external factors for their problems and frustrations.
Lack of Empathy: A lack of concern for the feelings or well-being of others, particularly if they are quick to harm or disregard others' suffering.
Substance Abuse: Some individuals become more prone to violence when under the influence of drugs or alcohol.
Extreme Jealousy: Possessive and jealous behavior that goes beyond healthy levels of concern.
Cruelty to Animals: Acts of violence or cruelty towards animals can be an indication of a violent disposition.
Unpredictability: Erratic and unpredictable behavior that is hard to anticipate or control.
It's important to remember that some people may show one or two of these signs without being violent individuals. However, if you notice a pattern of several of these warning signs, it is essential to take them seriously. Trust your instincts and prioritize your safety. If you are concerned about someone's violent behavior, consider seeking help from a trusted friend, family member, or professional support, such as a counselor or law enforcement, depending on the severity of the situation.
