Well, there’s that thing where Jesus was hungry and found a fig tree, which bore no fruit, so he just cursed it and caused it to wither:
[QUOTE=Mark 11:12–14]
On the following day, when they came from Bethany, he was hungry. Seeing in the distance a fig tree in leaf, he went to see whether perhaps he would find anything on it. When he came to it, he found nothing but leaves, for it was not the season for figs. He said to it, ‘May no one ever eat fruit from you again.’ And his disciples heard it.

I always thought that to be a bit uncharacteristically spiteful and hot-headed. I mean, it wasn’t even fig season, it’s a bit much to expect the tree to have fruit just because you want some right now, dammit!
And then just to kill it outright, I mean, couldn’t he just have let some termites loose on it? That was probably somebody’s fig tree, and that somebody was all looking forward to making delicious fig jam, or baking a nice cake!
The parallel passage in the Matthew gospel goes a bit more into detail (before this, by the way, he instructs two disciples to essentially go and steal him an ass and a colt, so that he could ride into the city in style, on the justification of ‘the lord hath need of them’):
[QUOTE=Matthew 21:18-22]
18Now in the morning as He returned into the city, He hungered.
19And when He saw a fig tree by the wayside, He came to it and found nothing thereon, but leaves only. And He said unto it, “Let no fruit grow on thee henceforward for ever.” And immediately the fig tree withered away.
20And when the disciples saw it, they marveled, saying, “How soon has the fig tree withered away!”
21Jesus answered and said unto them, "Verily I say unto you, if ye have faith and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, `Be thou removed and be thou cast into the sea,’ it shall be done.
22And all things whatsoever ye shall ask in prayer, believing, ye shall receive."

Here, he ties his killing of an innocent fig tree in with a promise of supernatural powers for the true believers. Also not exactly good style, if you ask me.
But then again, everyone’s allowed to have an off day now and then.
