The first example "someone take this" is indirect. Edit: upon reflection this could be a direct threat if the person saying it might make it happen by their influence alone. Like a mob leader saying "someone take out this trash"
The second example is even more indirect. Doesn't say he would do it. Doesn't say anyone else would do it. Doesn't even say what it is. A threat yes, but a veiled threat.
The third example is more of the same. Like saying "I hope you choke on it!" isn't a threat.
