Mark 11:12-25King James Version (KJV)

12 And on the morrow, when they were come from Bethany, he was hungry:

13 And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon: and when he came to it, he found nothing but leaves; for the time of figs was not yet.

14 And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever. And his disciples heard it.

Is this the way a man of G-d should act? Cursing a Fig tree that is not doing any harm by just being there? And not bearing fruit that is out of season, a pious man would do this?

Now let us continue with this chapter.

15 And they come to Jerusalem: and Jesus went into the temple, and began to cast out them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves;

16 And would not suffer that any man should carry any vessel through the temple.

17 And he taught, saying unto them, Is it not written, My house shall be called of all nations the house of prayer? but ye have made it a den of thieves.

John 2:15, it states that Jesus made for himself a scourge or whip, with which to beat the people in the Temple:

And when he had made a scourge of small cords, he drove them all out of the temple, and the sheep, and the oxen; and poured out the changers' money, and overthrew the tables... [John 2:15]

Those who 'bought and sold in the Temple' were there because of G-d's command. In Deuteronomy 14:24-26, G-d told the Jews to sell the animal they wanted to sacrifice for money, take the money to Jerusalem, and then after changing the money to the local currency, to buy the same type of animal and sacrifice it. Therefore the money changers and sellers of sacrificial animals were supposed to be there, as commanded by G-d:

Devarim - Deuteronomy - Chapter 14

24 And if the way be too long for you, that you are unable to carry it, for the place which the Lord, your God, will choose to establish His Name therein, is too far from you, for the Lord, your God, will bless you

25 Then you shall turn it into money, and bind up the money in your hand, and you shall go to the place the Lord, your God, will choose.

26 And you shall turn that money into whatever your soul desires; cattle, sheep, new wine or old wine, or whatever your soul desires, and you shall eat there before the Lord, your God, and you shall rejoice, you and your household.

Now let’s get back to Mark Chapter 11

18 And the scribes and chief priests heard it, and sought how they might destroy him: for they feared him, because all the people was astonished at his doctrine.

Feared him? For he committed a sin against G-d’s commandment that we just saw in Devarim - Deuteronomy - Chapter 14 verses 24 through 26? I would think a lot of people would be angry, he should be in fear. 

19 And when even was come, he went out of the city.

20 And in the morning, as they passed by, they saw the fig tree dried up from the roots.

21 And Peter calling to remembrance saith unto him, Master, behold, the fig tree which thou cursedst is withered away.

22 And Jesus answering saith unto them, Have faith in God.

The tree died for just doing what G-d ordained for it to be a tree that bears fruit at an appointed season. Everybody knew that figs were out of season.

13 And seeing a fig tree afar off having leaves, he came, if haply he might find any thing thereon: and when he came to it, he found nothing but leaves; for the time of figs was not yet.

for the time of figs was not yet.

Jesus robbed the man who planted the tree of his labor of planting and caring for the tree and of it’s fruit for the next season and following seasons. Jesus was a pious man, a man of G-d?
