Promised Mahdi(hgr) won’t be to advise cruel people in the world; not to do cruelty, avarice and seek domination! Justice can’t be established anywhere in the world, just by advice!

Establishment of justice in the world or some parts, needs just, justice seekers and righteous people to have power and talk with power to unreasonable people.

Advice is not sufficient for talking to the people who are intoxicated with outrageous power

They should be talked with authority in language.

Divine prophets( pbu th) invited the people to God through advice, just in early days.
