Missionary contacts highly vulnerable uncontacted Amazon tribe

[Jimmy Higgins]

No presumption whatsoever; the missionary went there to contact them, with the contact having been documented. It is well known that said kind of contact is highly dangerous for these tribes due to the spread of diseases, so guilt is a given even beyond the immense arrogance of thinking these people need to be converted to begin with. Whether he knew the risk or not isn't particularly relevant to the matter of his guilt.

You are assuming that the missonary (ies) go in without any preparation.

Like booster shots for the tribe?
