Blood on my hands?

Ezekiel 3:
18 When I say to a wicked man, 'You will surely die,' and you do not warn him or speak out to dissuade him from his evil ways in order to save his life, that wicked man will die for [Or in ; also in verses 19 and 20 ] his sin, and I will hold you accountable for his blood. 19 But if you do warn the wicked man and he does not turn from his wickedness or from his evil ways, he will die for his sin; but you will have saved yourself.
20 "Again, when a righteous man turns from his righteousness and does evil, and I put a stumbling block before him, he will die. Since you did not warn him, he will die for his sin. The righteous things he did will not be remembered, and I will hold you accountable for his blood. 21 But if you do warn the righteous man not to sin and he does not sin, he will surely live because he took warning, and you will have saved yourself."

James 5:
17Elijah was a man just like us. He prayed earnestly that it would not rain, and it did not rain on the land for three and a half years. 18Again he prayed, and the heavens gave rain, and the earth produced its crops. 19My brothers, if one of you should wander from the truth and someone should bring him back, 20remember this: Whoever turns a sinner from the error of his way will save him from death and cover over a multitude of sins.

James 3:
1Not many of you should presume to be teachers, my brothers, because you know that we who teach will be judged more strictly.
