man with no mind of his own

Yes. It's possible. The reason behind it is cowardice.
Because this man is afraid of negative reactions to his decisions.
And for him the easy way out is to let others do what they want.
But why does he feel this way.
Clearly he may not be right all the time.
And of course he will willingly accept the fault of his ways. Yet at times when he is right, he doesnt speak his mind.
And then ends up doing what others want.
And after people are used to his behaviour, he decides to wake up and act more proactively, he ends up being alienated.
Now the question remains will the fear rececde or will there be a relapse into cowardice.
