The most arrogant zodiac signs in my opinion are Aries, Capricorns, Scorpios and some types of Virgos. Aries is definitely the most arrogant. In Wikipedia they wrote about a chess champion Kasparov “known for his intimidating arrogance.”
One woman admitted that her Aries brother treated people around as if they were stupid.
One employee said that her boss treated her employees in a bad way and she reminded her Aries boss that she kind of needs them. (She behaved like if she is self-sufficient and independent of her employees)
Scorpios have a tendency to exaggerate their achievements, have a need for vanity and lack of tolerance towards what they find inappropriate in others, including details that others would forgive or not notice. What they find unacceptable is sometimes disputed and very subjective.
Capricorns have an authoritarian temper, dependent on social status and are sociopath. As soon as they achieve the high position, they start neglecting the needs of others and become selfish. Capricorns drain people with a total lack of trust in them, controlling excessively and being domineering. Capricorns always interfere into the affairs they know little about with their opinions, taking fragments rather than seeing the whole picture with roots of the problem.
Virgos become arrogant if you reject or criticize them, their closed ones or something that belongs to them. By the end it’s only about them, they don’t take into account what others feel. Virgos rarely forgive, have a pride of perfection and intolerant to mistakes or inappropriate behavior of others. Virgos get irritated easily and become despotic, losing humanness.
