If a node can predict that it is about to mine the next block, does it make it easier to tamper the blockchain?

The node which mines the next block can tamper in two ways:

  • Deliberately decide to censor a transaction, delaying its confirmation until a block generated by an honest miner.
  • Playing favorites when deciding which of two conflicting transactions should be confirmed.

You'll have to decide for yourself whether or not this is a problem for your needs.
