I'm not sure that the two Graccus brothers were " for the people ".
They were pure optimates who wants to preserve the old roman system, by recreating a class of famers who own their proper lands ( and who were initially the members of the first and second class )

Nevertheless, their godlike status doesn't save them :/

For the puppets plebeians tribunes:Yes.

But in Rome, the people was the upper and medium class of the society.
The poorest were considered as a bunch of stupid cowards.
